Health question: the tip of my dick started getting red / inflamed / spotty after sex / masturbation. If after sex, it will start hurting to the point where I have to stop. NEVER had this before. Could fuck for hours super rough and then crank one out like 5 times afterwards no problem. I've checked for STDs, nothing. Checked for UTIs, nothing. My urethra is also red pretty much all the time. What the fuck is this? This has been happening for like the last year and a half, maybe more ( haven't fucked the last year ).
