Anyone else get this?

Sometimes when I sneezed or after I urinate I’ll get a pinching/clenching pain in my perineum (area between ass and balls. I did a search and haven’t seen it mentioned. Also whenever I’ve masturbated a bunch or if I smoke A LOT of weed I’ll have better feeling with orgasm (although it’s never good). Maybe this is loosening up some pelvic muscles or something? Although pelvic stretches don’t do anything
