Anyway, im not sure when this started, but After ejaculation, and sometimes at random i Get this BAD stinging pain between my pelvis and rear, like on the inside of me. It lasts about 30 seconds or so..

Ive had blood in my semen, it seems like i dont last very long when having sex, and i dont think it was always that way, I dont know if its related but sometimes my penis shrinks, like really shrinks like small, and i get a pain in the head, and sometimes when i urinate after finishing when i give it the final push i get a bad stinging also, but its not the same as the after ejaculating.

Ive told a doctor about this before and she said the " Your to young for a prostate problem"
