What everyone else said.

Also I guess it sometimes scares me how much preference people have put into sex. It only makes me more apprehensive, like, holy shit, this person knows exactly what she wants and what she doesn't want, and I'm just plowing into the experience like an overexcited dog or something. But I'm not the kind of guy who doesn't get hurt by personal criticism.

I'd have to be insanely baked to ever have sex I think; it's prolly the only way I won't get irrationally stung by any minor criticism of my technique.
