I have been having a pain underneath near the tip of my penis and can't figure out what is up. I do not have any discharge( one time a small ammount of discharge when havinng a bowel movement) , burning urination, or burning ejaculation. The feeling is almost like i feel pressure underneath. The feeling is consistant it doesn't get worse or go away. A STD test i took was neg for Gonereah and chalymidia. Any ideas? My doc has me on antibiotics for septra for 2 weeks. One week in and no change.
