Ok guys I have a huge problem, I'm a 20 year old guy, and I recently got into a relationship. It was going great untill we tried to have sex. Its been three times trying, and everytime I have trouble keeping my erection. I dont know what's wrong with me. I'm very attracted to her, but once we switch possitions or after a little while of having sex it just dies down. The only reasons I can think of is bad circulation... please help me out!
