I’ve tried water base, silicon and mixed lube but it never last. Kinda sucks I spent $34 on this to enjoy just to put it down and go old school. I might be slightly above average, that said trying to insert in toy took so long sometimes that I I ended up softer then the toy material. When I did make it in other then pressure there was no other sensation no pumps, ribs etc. was like using a super thick rubber glove. All in all not worth it and huge waste can’t try before you buy and if it sucks can’t return it. So don’t waste money. Gloves and lube are cheaper and your hand has more ridges then this toy. Simple fact it had to be horrible for me to write a review.
