I’ve been doing this for a while now (a year or 2 now). When I’m at about 70-100% erection, I push my penis down ward and it pops, I used to see it like popping my knuckles, I can do it a few times a day, but I had to wait a while. But now I’m starting to wonder if it is bad to be doing this. Am I in any way hurting myself from doing this. My penis works fine, and sometimes I can’t avoid popping it (sex to where I have to push it down to get in the vagina, morning wood and having to piss, etc.). So is what I am doing bad, good, or neutral. If it is hurting me, please tell me. And also I would like to know what causes it. Thank you for your time.
