Hey, I am 28 and recently had a sexual encounter that makes me worry. I received unprotected oral from an escort 46 days days ago. Poor choices. I have not had any kind of sex since that day. 14 days ago was the last time i masterbated. 13 days ago i got a pink spot of skin on my penis that sheds every 4 days or so. (Day after masterbation. Lesion is right where my index finger twists) It doesnt really scab, or have any fluid on it, or coming out of it. it is dry but smooth and shiny. There are no lesions or ulcers anywhere else on my body. No swelling,pain,burning, or anything. I get jock itch through summer time on my gooch and thigh but have recently figured out after a few years that antifungal cream really helps with that. i tried treating this lesion with canestan cream thinking it was a fungas with no success. Tried a few others as well. Now all i see on the internet is syphilis hiv herpes etc... starting to get terrified. Please help to diagnose. I am planning std screening in 3 days.
