To Assume

Instapundit linked to a not-safe-for-work article.

It's about a kinky first date
that stumbled right out of the gate.

Eventually our author allows her date to have unprotected sex with her - and is then very upset when it turns out he has not withdrawn before completion.

He is upset too, to learn she's not on the pill.

As she makes clear, they'd had no conversation about withdrawal or contraception.

Rather, she'd made an assumption, and he'd made a different one.

Of course, they were both being idiots. Probably because their passions befuddled their reasoning powers. Which makes them, perhaps, victims of evolutionary psychology, which must favor natural reproduction, after all.

Reason tries to master sex,
which promptly turns around to vex
many a plan
of woman and man.
