Okay, so intercourse for around 15 minutes, but what about oral and foreplay?
When I have sex it usually lasts a couple hours if you include all the above. Usually we engage in a little kissing and touching, I go down on her for a bit, I bang her a little, then we take a break, kiss and touch again, maybe jump back to oral and repeat the process. Maybe move into the shower for a little fun. I like to stretch it out as long as possible. I don't orgasm until I decide to, so it doesn't end naturally with me suddenly losing my load, and I typically don't get bored if we keep changing things up. Never had any complaints from the ladies, either. Course you women are evil and would rather complain behind a man's back than actually work with him to have awesome sex, so... who knows.
God, so atrocious in the Old Testament, so attractive in the New--the Jekyl and Hyde of sacred romance.

If people are good only because they fear punishment and hope for reward, then we are a sorry lot indeed.
