Sometimes (not often, mind) I dislike being such a charming young man. I have a slow burn effect on women. I'm not great in the pickup scene, but I can navigate my way through the treacherous no man's land called the Friend Zone like no one's business.
Basically, if I have a friend that hasn't outright said she wouldn't sleep with me, chances are I can get her to. With time, of course. Time or alcohol. No need to pair the two.
