Hello @ManyWords99!
They are really great questions, I have been using the Njoy for over 6 months and after lots of trial and error (but all fun!) I’m pretty sure I’ve found the best and quickest method for giving myself dry prostate orgasms with the Njoy Pure Wand, this is what works best for me and it’s not the easiest to explain but I’ve tried to be as detailed as possible!
BEST TECHNIQUE FOR USING THE NJOY PURE WAND TO GIVE YOURSELF DRY PROSTATE ORGASMS (MEN)
(By “dry” I meant that you have an orgasm without ejaculating, which means that you can keep going, both by having a long orgasm of several minutes and also then going back into the technique and giving yourself more orgasms without a refractory period. Also, there are other techniques, but this is specifically the one that makes me have this orgasm in the quickest amount of time)
1 - Make sure that you find a private space, where you can be by yourself and you have 100% confidence that you will not be disrupted, as to have a prostate orgasm you really need to be as relaxed as possible and to have 100% focus on making yourself feel good
2 - Get naked (or wear clothes that will not get in the way of your arm movement or the anus area) and make sure that you have your Njoy Pure Wand (or any sex toy that works for you), a large towel, plenty of anal-safe lube and a device (phone/laptop) that you can use to either play romantic music (as prostate stimulation is a lot to do with in your head and being as relaxed and turned on as possible) or porn (but this requires you to not be distracted and to focus on yourself, so I find that it is best to not watch any porn)
3 - For this technique, lay your towel out either on the floor or the bed, basically you will need to be very close to a wall in order to get into the position to stimulate your prostate
4 - Now, before you lie down, I would recommend that you go to the bathroom and run the tap to warm (but definitely not boiling) temperate and place the Njoy under the water to warm it up, as it feels better that way and is less of a shock if it isn’t freezing cold (it is made of metal)
5 - Once you have started playing your music/video from your device (now make sure that you don’t touch it again, as you need to focus on yourself) lie down onto the towel on your back (with the back of your head against the towel, you can put a pillow if that is more comfortable, and with your back flat against the towel, but making sure that you are comfortable) and move yourself horizontal along the ground/towel so that you bum is about 10 to 20 inches away from the wall (or whatever distance is comfortable for you for the next step)
6 - With your back/head/bum flat lying down on the towel, making sure that it is fully covering all around your bum as it is very likely that there might be lube on it by the end of the session (or worse, if you know what I mean… I will explain later how to avoid this), you then need to raise your knees up towards your chin and then stretch them out so that the flat’s of your feet are flat against the wall, so that the tips of your toes to the base of your foot are all flat against the wall). You then want to re-adjust yourself so that you are as comfortable as possible in this position, but making sure that you back/head is flat against the towel, your feet are flat against the wall, your knees are bent towards your body (but not touching it, kind of like a sideways squat) and, most importantly, that your anus is (this is a weird analogy sorry haha) aiming towards your feet (basically, not facing down towards the ground)
7 - Once you are in the position, make sure that you apply lots of lube to both your anus and to the big bulb of the Njoy (as this is the side that I use, by all means you can use the smaller size, but I find that I have orgasms much quicker with the larger bulb). The best tip that I have learnt about lubing up is to make sure that you put on enough lube so that you will not have to re-apply any lube later in the session, once you put the Njoy in you don’t want to need to have to take it out at any point, other than after you have finished your session
8 - Once you have lubed your Njoy and anus, you can now start using the sex toy, I have listed below the best techniques for holding the toy:
a) If possible, which will normally be at the start, try to hold the Njoy with one hand and you will want to hold the other end of the Njoy (the end that is not inside you) as if you were holding your penis, so the same grip, I find it best to hand my wrapped hand just underneath the small bulb so that I can have a really solid grip of it
b) This is the “Plan B” for if you hands get tired (or if you need to thrust the Njoy harder to make yourself orgasm, so I will frequently move to this hand position after 10-ish minutes) you can have your right hand in the same position as for a) but then use your left hand to support the weight of the Njoy, I would normally place it lower down the shaft of the Njoy and use it to both support the heavy weight, but also to help to thrust the Njoy even faster and harder inside and against the prostate
9 - After you are holding the Njoy correctly, you want to spend a few minutes getting yourself in the mood (basically, feeling turned on in a “romantic” way, as that seems to work best for prostate orgasms) and you can slowly brush the large bulb of the Njoy against the rim of your anus, mixing the lube against your anus and the toy, while also slowly preparing your body for the next step…
10 - After a few minutes, you want to slowly (very slowly and carefully, you do not want to hurt yourself in anyway) push the large bulb of the Njoy into your anus, BUT (this is REALLY important) once you can feel that the entire large bulb is inside, DO NOT PUSH ANYMORE OF THE NJOY INSIDE YOU, your prostate is literally only an inch (or two) inside you so just having the large bulb “pop” itself into place inside you is far enough, keep the “stick” and small bulb fully outside your body
TO MAKE THIS POINT REALLY CLEAR, YOU DO NOT EVER WANT TO PUSH THE NJOY ANY FURTHER INSIDE YOU THAN RIGHT NOW AT THIS POINT, THAT IS THE SECRET (FROM MY EXPERIENCE) OF GIVING YOURSELF PROSTATE ORGASMS AND MAKING SURE THAT YOU DO NOT “ENCOURAGE” ANY UNWANTED BODILY SECRETIONS TO START TO COME OUT!!
11 - From this point, you will NOT be pushing the Njoy any deeper at any point for the entire session, but instead you want to do a PULLING motion upwards with your hand (vertically, or at a slight diagonal angle upwards in the direction of the wall, not in the direction of yourself, that is very important) as this will move the large bulb up in the direction of your prostate (it is located directly behind your penis) to push against it
12 - Each time you pull the Njoy upwards/diagonally towards the wall while your legs are up in the air and your feet are flat on the wall) this should only take a second and at the start you want to do this softly, if you go too hard you will give yourself a short wet orgasm, which will basically make you ejaculate a mix of pre-cum/urine, which you can keep doing lots of times and is very fun/pleasurable, but if you even so much as do one wet orgasm like this, it’s really unlikely that you’ll be able to give yourself a dry prostate orgasm in the same session, as the dry prostate orgasm seems to be triggered by a build up of ejaculation and pre-cum inside you, but I’m no scientist haha although that seems to be what is happening
13 - After you pull the Njoy upwards for a second, up against your prostate, you “release” the Njoy from the prostate by slowly pushing it back into the first position (step 10) and then repeat the process, again making sure that you do not push the Njoy any further inside you than step 11 because that is further away from your prostate and will not give you a prostate orgasm
As a quick point to note, it is very likely that throughout this session you will not give yourself an erection, even during the orgasm! No idea why this is the case, you’ll make lots of pre-cum, but for some reason no erection, oh well 
14 - Now you want to repeat this process of the up/down motion with the Njoy, building up momentum ONLY when it feels right and this very gradual process is likely to take between 10 minutes and 1 hour, but if you repeat steps 11 to 13 again and again, but the only difference being either the speed (if your body is saying it wants more than anything for you to rub your prostate faster) and pressure (if you body is begging for you to rub your prostate harder). Do make sure that you don’t rush this, it has to be natural and if you do try to rush going faster/applying more pressure before your body itself is asking for it then you are unlikely to reach the dry prostate orgasm stage
15 - Now, this last step is the dry prostate orgasm itself (basically, after finishing the session, slowly (very slowly) take the Njoy out, clean it and yourself as thoroughly as possible and definitely throw your towel into the washing machine) and I personally find that I will have spent about 15 to 20 minutes getting more turned on and feeling better, but having intrusive thoughts in my head that say:
“Come on, it’s been ages, let’s try to hurry it up”
“Maybe if I push harder, it’ll make me orgasm”
“I must be doing something wrong, I’ll try this”
Basically, ignore your thoughts, relax your mind, focus on your body and what your body is asking for, this is NOT like masturbating a penis where it is trying to ejaculate, this is the very careful process of massaging a pleasure point (the prostate) until it feels so good and has so much built up sexual energy that your body loses control and gives you an amazing, continuous, dry, full body “super” orgasm because it literally needs to orgasm more than anything! So take it slow and, like with life, enjoy the process, don’t focus on the end outcome, as if you do it’s not going to happen!
I always find that the dry prostate orgasm “emerges” out of no where and takes over my entire body without any warning, literally one second I’ll be thinking “come on, why isn’t this working” and then BAM!!! A few seconds later, it’s as if my body has folded in on itself and is forcing me to orgasm in an attempt to unleash all the built up pleasure from rubbing the prostate! The dry prostate orgasm is THE BEST ORGASM as, unlike a normal ejaculatory orgasm from a penis for men which lasts 5 to 10 seconds, THIS orgasm (as there is no ejaculation) can last for several minutes and rather than being focused around your penis area, it seems to take over your entire body! I find that during the orgasm itself, that is when I am going as fast as I can with the Njoy and applying as much pressure as I can on my prostate, not because I am intentionally choosing to do it, but because my body is literally in auto-pilot and going CRAZY in ABSOLUTLE PLEASURE!
Honestly, it’s like you’re out of control and trust me, you are going to make some bizarre, loud, deep grunting noises, but that’s only as another way for your body finding a way to cope with all the incredible pleasure! Once you’ve had an amazing orgasm, either you can take a break (which I do, as not only are my arms usually exhausted but I am sweating and emotionally drained) or jump back in straight away (which you can do, but do make sure to not hurt your anus).
That is pretty much all the advice I can give, do try to find the best position that works for you, be as safe as you can (NEVER hurt yourself, as you do not want to injure the inside of your body) and do have a look at other advice online, there is plenty of it and lots of very different techniques! Have fun and do let me know if this works for you, I only discovered prostate orgasms 6 months ago and have been wanting to spread the word about them to as many men as possible as they really are absolutely amazing orgasms!
I hope this is helpful and do ask if you have any questions! Thank you so much for your Aneros recommendations, they are really useful and I’ll 100% give the MGX a good go!
