To be fair, there's a lot more (or at least the prospect of a lot more) emotional investment in the act of sex than there is in taking a leak. Even a character having sex with someone who they're not emotionally attached to, or having the most boring sex ever tells you more about that character than the most exciting of trips to the bathroom ever could.
