I am only 19 and i am having erection problems. I dont know what to do. When i am pleasing her in any way i become hard and it stays hard until she starts to pleasure me. When She begins to play with it either hand or oral i dont become limp but i become just a little hard and i dont really feel anything. I dont understand because i can masturbate and it will stay hard constantly. When i drink sometimes it will stay hard. I dont understand why it will not stay hard. It is aggravating me and it is embarassing. I wouldnt think i need viagra but i may. I dont know if there is anything i can do. Please give me any advise or anything at all.
