too much information

one of my long-standing male girlfriends, scott, is in town. we were talking about sex, because for some reason my car is similar to a high school boy's locker room (in conversation only, not smell!). suddenly he blurts out he has an unusually long tongue, then proceeds to show me. what did i do? i nearly wrecked my damn car into a car in the other lane. in the future if all friends could agree not to show me their body parts while driving that would be great.
