Since the past month or two whenever i try to masturbate, i only start to get hard as im about to climax and if i stop for 5 seconds i lose my sexual drive and i go soft again. Whenever i orgasm, i dont ejaculate as much sperm as i usually have in the past and the climaxes is disappointing. What strikes me as odd is that during school, i still get random erections but when i want to try to masturbate, i cant get a erection. I see all these posts saying its probably stress, etc. but in my opinion i'm not that stressed. I'm really scared because i really dont want ed. Its hard for me to talk to my doctor about it since i would have to ask my parents to schedule an appt and it would be really awkward. So please respond asap. im going to try and stop masturbating and hopefully i can replenish my sexual drive.
