Every since I got treated for Chlamydia I've been having this weird sensation (not really and itch or pain) inside the head of my penis a little below the opening.Its been going on for almost half a year now... I've done multiple test and have no STD or STI (even took a test last 2 weeks ago and still nothing)... I've went to Dermatology to see if its a skin thing and no luck... I've gotten a Cystoscopy and no luck.... the "sensation" last no more than 3 seconds and happens daily. I know my doctors said I'm clean but I fear one day upon trying to have a child or have unprotected sex I may pass something unknowingly unto my partner...... and that'd destroy me..... Its not an issue with my detergent or soap, I've changed them multiple times, I've used treatments for yeast infections because I thought it might be there and still no luck.... Right now I'm out of options and just looking for suggestions on what it could possibly be. Hopefully someone can help.
