Being sexually active =/= having just as much sex with people as Marky. They're grown women, I doubt anyone sane cares that they aren't virgins at this point. Ken's slept with two or three people, Marky around ten to twelve I'd guess. We're just here for a show, so no need to get your panties in a twist.
I was also able to figure out that date through her rateyourmusic, tumblr, and that old r9k screenshot.
