So I have been going out with this girl for a few months and I am having a problem keeping a boner. Now, I can get and keep it when we are just cuddling or grinding or whatever but as soon as she tries to touch it with her hands or mouth...It seems to have a life expectancy of 20 seconds or less. I don't know what the fuck the problem is. I'm 22, and hand/blowjobs have never worked for me. Has anyone had this shit happen to them before? I really like this girl and I can't think of any reasons for my dick to not cooperate.
