I think the most important criteria is whether you really care for somebody (aka love) and not what their reported skills are. Do ya want to ask for a resume'?

One of the pleasures is discovering each other, that is assuming you are in a relationship long enough to do that. I suppose for a one-night stand, if you are into it, that experience, p-size, level of fitness, may play a part...but I'd take a 1st timer who I love anytime. Otherwise, ya might as well get robo-dic_.

Unfortunately, I can relate to his philosophy. THe problem being, my ex didn't tell me that was his rule until AFTER we slept together.

If he won't get tested, then I think that answers everything right there. If he cares about you and the relationship, he'll do it.

Nope, too many bugs out there. Also, eventually you'll become "just one of the girls he slept with."
