Perhaps this should be its own post, but I'll post it here and let the moderators decide.
I started trying to cure myself of this addiction a little over a year ago because I was having copulatory ED. Since then, I have had successes and failures, relapses and such, but I am currently over 60 days into my recent stretch of no PMO, and I feel better than ever.
I've been waking up from time to time with partial erections, and even get a few semis out in public while riding the subway and things like that (though these are less common). What has happened to me a few times, is that I'll wake up with a full on erection that is actually a little bit painful. I hadn't heard of anything like this before in anyone else's experiences. Is this common? Is my body not so used to full on erections that the ones I'm getting are hurting a little? Will this go away? Could I have damaged my penis from years of unhealthy prone masturbation?
These days my best erections though seem to be the ones that hurt a little bit. They are the only ones I'm getting where I feel the penis is fully erect enough for sex.
