My bf and I were hanging out the other day playing a Bible quizing game on the couch. My legs were resting on his knees when later on into the game, he was falling asleep (I guess--he was quiet and had his eyes closed) and I guess one of my legs slid closer to his crotch.... I felt something poking my leg (it felt like it was getting big then he was fighting it but it was getting big then going back and forth like that a couple times). How do I ask him if it was an errection and how do I being it up??
