Why does sex seem to get a pass for "you can't control your biological impulses" when other drives don't?

That isn't really the problem. The problem is more complicated than that. It includes:

Delusion: Modern peoples think birth control is more reliable than it really is.

Guilt: I have seen studies that indicate that certain populations of women have a high incidence of pregnancy because they feel planning for sex makes them a slut, but just getting swept away with emotion makes it "love" and that is somehow OK. So, birth control is proof that "I am a slut."

Religion: Some religions (Catholic church) forbid use if birth control.

I am sure I could add to that list, but I have other things I need to do.
