I've found that I prefer sex when I don't cum... generally because if I do cum I usually cum faster than I want to, and I'd much rather fuck for an hour than cum in two minutes. Anyone else have a similar preference?

And you don't get blue balls?
Well my boyfriend takes his time when he knows he's about to cum.. he slows down his pace and we take it down a notch if he wants to go longer without cumming so fast. We've gone about two hours before using this process, it works. But he always ends up ejaculating to avoid pain......
