After going to the toilet and afterwards having an intensive orgasm (or sometimes even without going to the toilet - stool) i experience great pain in the perineum area and mainly in the anus itself. It feels like a cramp and it lasts from 5min to 2 hours. There is nothing really i can do to deminish the pain (sitting, lying, walking).
I don't know whether this is related to my going to the toilet (since this "cramps" can appear also when i go to the toilet the day before and have a intense orgams the day after) or with the intensity of the orgasm (if i hadn't had one for a couple of days), or if it's a problem with the prostate (proctitis, prostatitis, proctalgia fugax, levator ani, maybe even cancer). Haven't been to a doctor yet but i should probably go as soon as possible. Any help (suggestions, experiences, etc.) would be much appreciated.
