Hi I'm 16 and I'm scared I have Premature ejactulation.. When I watch porn I canot steadily masturbate for 3 minutes. I have to stop and start every 20 or so seconds. When I do the" stop and start" I can last for about 10 minutes. but when I'm not watching porn I can go steadily for 15-20 minutes. I started masturbating about a year ago. And I'm wondering if I have it or not.. Please help me out and let me know if I have it or tell me what I should do to prevent myself from having premature ejaculation! Thanks!
Oh and I masturbate probably 2 times a week, and also I cannot last a minute while steadily masturbating, while watching porn, not 3 minutes.
