This was a random ED pharm spam, nothing to really distinguish itself from any of the other few that manage to slip past my defences. But the subject line of this one did catch me before I deleted it:

"How Can You Tell If Your Girl Is Satisfied (Sexually)?"

My immediate, somewhat bemused reaction: "Uh....she tells me?"

Seriously, maybe I've just been lucky with my partners, but it's not that hard to tell that you've done a good job. Especially if your partner is someone you, y'know, have conversations with that feature polysyllabic words.
