Hi, I have a very irritating problem. For the past 8 years, since I was a teenager, I've periodically had intense pain after ejaculation. This only happens once every 2 weeks or so, and I've had it from sex and masterbation.
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, and there is no common factor to relate it happening to sex and masterbation (as far as material objections like latex etc). It seems like there might be some slight swelling during this period of 1-2 hours also.
The only thing I can think of is sometimes when I exercise for long period of time my groin has a distinct smell from it (bad). This isn't always the case though, I can run 3 miles one day, and stink like this, and the next day I can run 3 miles and smell perfect. I have no marks/bumps/warts etc in my genital area.
I've searched the internet for many hours on this and I can't find an answer, thanks for your time.
