How do I turn my boyfriend on again after we already had sex one time? I am a pretty good looking young girl and I like to have sex more than once a day if its on the weekend, and not planned sex either. Like if I feel like my boyfriend looks really good I want to show that. But after we have sex it only lasts for like 5-6 minutes and then he's done, and I am just getting started. But he says he's tired and can't possibly do it again and it's like a big deal for him. He's only 21, so I'm just wondering maybe he has a problem? He eats A LOT OF CRAP like sweets and stuff: maybe that has something to do with it. I tried to get him to see a doctor but I think that only pissed him off. A healthy sex life is EXTREMELY important to me. What do I do?
