I've had pretty good success playing the "questions" game to build rapport and intimacy with women, particularly over text message. But I got this question from a girl last night and wasn't quite sure how to handle it.

How would you effectively answer this with a strong frame while at the same time not coming off like a manwhore? (I had had sex with another girl two nights before, but ended up telling her "a few weeks ago.")

EDIT: Great lines! I probably should have been clearer up front in asking for recommendations that would work well over text message. Unfortunately I've found a lot of the cocky/funny responses don't necessarily translate well over SMS, nevertheless some solid responses!
