I think I might have ED or some signs of it. These days I cannot get a natural erection unless I stop jacking off for about a weeks time. At the end of that week I start getting natural (and hard!) erections again, but during that week I have to use manual stimulation, and when it gets erect it's mainly lazy erections. Also, the weirdest thing happened today. So for about a week now ive tried to prevent myself from masturbating to get better erections. Today is the day after I jacked off at the end of that week, and I kept sensations that I was going to get close to orgasming while unerect. This is the first time I can recall this has happened. Then, while I don't feel anything when it happens, infrequently while jacking offI get red spots/splotches on my chest. And I know that ED might stem from cardio problems but I took my blood pressure the other day and it seemed fine? Right now i'm panicking a little bit, especially that this is happening while i'm only 18... Help?
