I don't use my fleshlight much, but they are much better than the old "Doc Johnson" junk. I just don't find hand use of it very satisfying, I'd rather play with my dick directly. I've heard of guys putting it between the boxspring and mattress to fuck it.

I do want to try the Onahole, though.

These might help you make up your mind, though they need more lube: Fleshlight research

I would definitely recommend the FleshLight. I had my first one for about 4 months, got it from Amazon with next day delivery to a collection point.
Only problem was that I seem to have split it, partly through a lot of use (2-3 times a day) but probably because of trying to get two cocks in it at the same time.
Some people say that works but I wouldn't recommend trying.

Anyway I've got a new one now and wanking has returned to its previous levels.
