I have a small bump on the under shaft of my penis. It does not hurt, itch, or cause me any pain unless i squeeze it hard enough. Even if I just touch it, it does not cause me pain. I have only tried once or twice to pop it. It is not what appears to be a pimple. I think it might be Penile Lymphocele however I don t want to make assumptions. I am considering going to get a culture if it does not go away on its own. I am sexually active and last had unprotected sex (with my girlfriend) around 1-2 weeks ago. I masturbate daily and sometimes more than once and I have read that this might be detrimental (if indeed it is lymphocele) and starting today until I can seek medical attention will stop having sex or masturbating until it goes away. I have never previously had anything related to this even though my sexual patterns have remained pretty constant for the past several years. What could this be? Please help.
