I recently bought an Adonis penis extender so I can please my girlfriend more easily, Im one of these poor sods who's not lucky enough to have a big cock. However, im a little shorter than the inside fit for the sleeve, so theres a section between the end of my penis and the head of the extender thats still "squishy*.
I'm wondering if anyone has any suggestions for ways to fill that last part safely and easily, so that the whole sleeve is "full"?
I could be wrong, but I think I've seen people mention that you trim the end of the sleeve a little to fit you better?
As for filling it, I'm really not sure what would be safe and hygienic. Sorry! Hopefully someone will know a little more than me :)
I noticed that this one http://www.lovehoney.co.uk/product.cfm?p=30930 comes with a filler plug and it is clearly stated that you can trim it.But nothing like that is mentioned about the one you have..Hmm..Sorry,hope someone from the staff will comment on that on Monday..or one of our more experienced users.
I don't have any experience with that product but would filling the void with a cooling/ warming/ delay lube be an option?
Doc Johnson do one that you trim to fit, I have a very similar one to this called tommy gunn cyberskin sleeve, LH don't stock this one though, if you wear a sleeve and there is a void at the end it is just going to bend and be uncomfortable for you both. I would opt to trim a bit off at a time until you fully fill the sleeve, for her comfort though I would recommend the cyberskin or UR3 type ones, the jelly ones,rubber ones are too hard and unforgiving in my experience, and I've tried a few,my next venture into the penis sleeves is going to be the vixen collosus :),hope this helps
This is interesting, as I am looking to buy my first cock sleeve. Will look out for one that I can trim. Cheers for the advice 
Here's the "industrial" way, simply fill it with clear silicon sealer and wait for it to cure(few days/week) once set it's safe no worries though trimming it down is the cheap quick way!
Hmmmm, bit of caution required using a silicone sealant as it can evolve acetic acid during curing which if your not careful could damage the sleeve or burn\irritate skin,I wouldn't recommend using sealer
