Does a vagina feel better than your hand? Real question....
I don't know about the OP, but for me there's no comparison: a vagina just feels unbelievably good, almost without exception. What it isn't so good at though is exerting pressure or varying the way it interacts with your cock. With your own hand, you can vary the pressure and the movements exactly how you want it to be at any given time.
Suggestions would include trying different, various condoms, trying different positions (e.g. doggy style often feels tighter, a missionary-style position that forces you to thrust quite vigorously might also help) and cutting back on the wanking, and/or rubbing more gently when you do it.
