I've periodically had intense pain after ejaculation on the tip of my penis or let me say in mu urethra . This only happens once every 2 weeks or so, and I've had it from masturbation.
This pain will happen anywhere from 5 min to 30 min after I ejaculate, and the pain will stop temporarily when I urinate, sometimes when I urinate it even feels good. This also causes me to feel like I constantly have to urinate. This pain always disappears after an hour or two, and never happens unless I ejaculate. I don't understand this at all because it only happens once in a while,
