Had the same issue don't know what happend may be it's due to overmastrubation do you have morning wood?
Could be you just de-sensitized yourself by overdoing it. There’s no right or wrong amount of masturbation, but everyone’s different, so that amount may have been a little too much for you. The fact that your penis skin changed appearance & is dry sounds like irritation, which again points to overdoing the masturbation. I think if you dial it back a bit for awhile, you may regain feeling & ability to achieve erections.
Well friend I've been a chronic masterbater for basically most my life. Im almost 34 my first masturbation was when around 7 or 8 accidentally discovering porn. My answer is too much masturbation.
Also honestly not being able to get a erection my girlfriend is beginning to think maybe I'm gay. Does anyone know how that feels? Sometimes I think to myself am I?
