Thanks for the sweeping generalization dude. No reasons to not have sex? I think not. Here's a few: stds [there's a good chance of getting those if you're sexually active, and condoms won't protect you from it], pregnentness [that can happen even with protection] Those reasons are enough to keep me from having sex (and I'm not a woman). I can't think of any reason to have sex. Mastribating is just as effective.
There isn't a good reason to because you are here and the lover is on the way. When you leave then there will be a good reason. (teasing)
