I think I have performance anxiety when I jerk off essentially, plus the problem of decreased sensation from being circumfucked.
I managed to do nofap for 3 weeks now, today my dick felt like it was ready to go and I might actually be able to have a successful fapping session, but I didn't jerk off right there, I waited for later...and then my ability to get as aroused was gone again by having made jerking off into an appointment in my mind, filled with anxiety, will I be able to pleasure myself or not...so I failed, didn't really feel good (like either almost no pleasurable sensation or premature ejaculation right away if I hit that point where I get a hit of pleasure throughout my cock), and then the ejaculation was painful (happened to me before, when I don't fap for a while, the first nut will be painful).
I don't know, I hope it'll work again soon at some point (once in a blue moon I feel something), I'm at my wits end with my cock, what a punishment to not even be capable of pleasuring yourself when you're not getting pussy.
I don't think I get much a morning wood either, but spontaneous erections yes.
