I'm a 20 year old guy and still a virgin. I have been trying to get into a relationship but keep getting rejected. However there is one thing that makes me nervous about having sex. When I masturbate, most of the time I finish quite quickly and I don't want this to happen during sex. Most of the time I am masturbating quite quickly and I guess this could be why. I can last longer if I slow down but I normally get bored and speed back up again. Is there any way to help me last longer so that when I do have sex I don;t finish quickly?
