Some times have a sting in rectum. itch feel in urethra , testical pain. yellow tint semen , can it be due to pelvic floor ? all tests have been neg was told to see a pt? can also feel rectum tighten on its own and i relax and it loosens?

It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. It would be prudent to see a doctor. Wish you good health!

Rectal spasms or levator muscle irritability may be part of the problem but wouldn't explain itchy urethra or testicular pain. I recommend having your physician or a urologist inspect the anus & perform a rectal exam,evaluate the prostate and examine the testicles & then advise you.

Your symptoms do not indicate anything serious since all tests are neg and I hope also had a physical including the prostate. If so try not to concentrate on your symptoms and wear a support underwear, eat healthy, exercise, keep busy and if you want to- do relaxation/meditation so you do not worry about all the symptoms . do not self diagnose. I think you will be fine
