I am 21 years old male and I am a virgin, I think. I haven't actually had sex but I've experienced hand-job and oral sex before.
I suffer from premature ejaculation syndrome. When I masturbate without any stimulation from porn etc, I can last for about 1-2minutes. With porn or during oral sex usually it's usually only about a minute. I hate it and it's making me depressed.
Thinking about something else to avoid ejaculating too quickly does help to a certain degree, although not each time and not always so significantly. But it's hard to keep on focusing on other things while actually having sexual intercourse.
The thing is, I haven't always been suffering from premature ejaculation. I have been masturbating since I was 7-8years old, despite the fact that I hadn't reached puberty back then and I remembered that I used to be able to last longer when I was a teen. I can't really pin-point as to when it actually began but I would give a rough estimation of when I was about 18-19years old. I can't remember by hard, but that was probably the time when I began watching porn and masturbating excessively too.
I remembered that one of my highschool teachers once said that excessive masturbation can cause over-sensitivity or no-sensitivity at all. In other words, it can cause premature-ejaculation (due to over-sensitivity) or erectile dysfunction (due to lack of sensitivity). I don't know if it's because I am inexperienced with sex that I am ejaculating too quickly but I was beginning to wonder if excessive porn and masturbating is the cause of my premature ejaculation syndrome.
I have also noticed that, while masturbating, I would ejaculate quicker if I was lying down or sitting but I can last significantly longer if I was standing or kneeling. Does that make sense? I can't think of any explanation for that.
Can anyone give me some advice and help please. It's really screwing up my life.
