I am a 21-year old student enrolled in a university. I believe i have ED, or at least psychological ED. I have recently become sexual active, and have has sex with 3 different women the last couple of weeks. The first time I was able to get an erection, after foreplay and oral sex, but it didn t last and went limp very quickly after vaginal penetration. The second women was pretty much the same scenario. The third woman was the worst experience - Even if I was totally into her (most beautiful woman I have seen) I was unable to get an erection at all. Even after she gave me oral sex. There was only certain instances where it got a little bit erected - never fully erected - but even that didn t last enough to put the condom on. This has been troubling me for several days now. I noticed that I am not getting any erections throughout the day, and I have not had a full erection since I began to be sexually active. I am thinking of scheduling an appointment at my school s Health Services. Would their health services be able to give me a sample - or even a prescription of viagra? I can schedule an appointment with someone with an MD.
