Hi!
Lesbian here 
me and my partner recently bought a strapless strap on. Both of us are able to get the dildo in pretty easily, but inserting the end for the wearer is painful for both of us, so we haven’t really been able to use it properly. Has anyone got any tips for this? (excuse the pun). Would REALLLLLY like it to work 
My girlfriend found these difficult as soon as she got wet it was hard to keep in place, harness kits are the way forward
I didn’t get on with the strapless one either. The wearers end is quite bulky and firm, and you’re holding in the entire weight of the toy. Then add in some slippy wetness, bc obvs its all very hot, you’re more fighting to keep hold of it, more than do the do.
If you want to persist with that toy, you could repurpose a pair of underwear, cut a hole at the front for the penetrative end to come out of and then the underwear will ‘cradle’ the toy and take some of the weight off your vagina muscles.
I got a harness type and much preferred that, they usually have a pouch that a bullet can slide into for the wearer. But if you want to have something inside you also, you could wear some jiggle balls.
I often wondered about how well they stayed in while in use . The first ones came out about the time my wife became unable to have pretty much any kind of sex . I noticed that all the makers pretty much followed the original design for the user . Having many anal toys it is amazing how many rather expensive prostrate massagers do NOT stay in very well . I think the makers of the no harness "strap ons " should do a little research into the issue . I would be more than happy to be the receiver for such research . I remember the hassle it was for my wife to assemble her strap on , we never tried the panty models . They visually turned me off . Good luck on your play time .
The only way we could get a strapless strap-on to work was for my wife to use it in conjunction with a pair of harness briefs. The briefs hold the short end inside the wearer and the long end pokes out of the hole in the front of the briefs .
That being said she never found it comfortable and quickly reverted to a standard strap on.
From other reviews on this I maybe wonder if it’s a toy what sounded better in theory rather than the reality 
Exactly.
Totally recommend strapless strapons, guess it all depends on what brand you get. Love out big red feeldoe but would like it a bit more if it was not as hard and firm. They dont work very well with out a harness, we were luck that one of our harness suits it perfectly, looks great too
dang!! I have to try
