Im 17 and ive been having sex for about 2 months. However just about last week I was doing it and I lost my erection. I tried doing it the day after and the same thing happened. This wasnt the first time I encountered this. I had it before but it returned to normal after a couple days. This time is different because im starting to lose feeling. The bottom portion of my penis has become numb. Now I cant even hold an erection for a long time. I tried masterbating and it becomes hard for a while but soon softens in a matter of minutes. This doesnt seem too good at my age because im supposed to be at my prime. Im not so sure what im dealing with but if you have any comments please say so. Thanks.
