Over the past week, I have noticed a slight pinching feeling in the tip of my penis. It feels comes and goes but has feelings that range from a tickle to a burn to a pinch. It almost feels like I have just a little bit of urine trapped in the tip of my penis. I do not know if this is related or now, but I have noticed when I ejaculate, sometimes there is a jelly like substance at the end that comes out in the end of an orgasm. It is white and other than the fact that I touched it I wouldn't have noticed it. I had unprotected oral and intercourse about 3 weeks ago in a drunken one night stand. I do not have any pain when I urinate, no discharge, and no noticeable rashes or skin ailments. The feeling comes and goes. When I look up symptoms it seems like prostatitis but I am not sure and am freaking out because I have had unprotected sex with my girlfriend regularly before I noticed this weird feeling in the tip of my penis. I do not know of it is my anxiety that could be causing this, because when I do not think about it and occupy myself I do not feel it. It does not hurt to urinate whatsoever, I know this is a less common symptom with chlamydia and gono and I think I'd have discharge or burning when I urinate.
PLEASE HELP
Thank you
