Hello. I believe I'm posting at this point because of extreme guilt, shame and anxiety but I'm looking for extra assurance to what has been laid out to me.
I am a 36 year old white heterosexual male who is married and in a monogamous relationship for nearly 8 years. Prior was another married monogamous relationship of 7 years. Prior to the incident I am about to describe these were my only sexual contacts.
On March 28, 2018 I had an oral sex only encounter with a white female whom I believe is also hetero (but not sure). I came into contact with her through communication on Adult Friend Finder (I was originally there for just pics & vids but unfortunately got curious). Prior to meeting we discussed oral sex but only on the grounds of "no STDs" which we both claimed to have none. The encounter also included deep French kissing. I performed cunilingus on her (5 to 10 min), she then performed felatio on me though I was unable to maintain an erection as guilt was already taking over. She messaged my back for about 10 min to try to get me to relax and I then masturbated with my own saliva to no success. Somewhere along the line I fingered her but can't remember when or for how long. At this point I said it isn't working, showered and left. I also brushed my teeth and used mouthwash before and after said encounter.
Feeling extremely guilty I contacted her and asked once again if I had anything to worry about STD wise and she said no, that everything was clear in her last appointment and had not been with anyone in the two months since her appointment and "stranger sex" was not the norm for her. She suggested if I still felt the need to go get tested.
I went to my local Planned Parenthood at 5 days post exposure, explained the situation and they tested me for HIV (rapid), Syphilis (RPR), gonorrhea & chlamydia (blood, throat, and urine). All were negative but they advised me to repeat the tests 2 weeks later (19 days post exposure) all negative again. I returned on May 3, 2018 (5 weeks, 1 day) after having diarrhea on the weekend. All tests once again negative. I felt OK for a week then anxiety picked up again after noticing pinhead sized hard white dots on the underside of my penis shaft. The NP examined and assured me it was nothing STD related and stated testing would only be for peace of mind. I opted to test HIV only which was negative. On June 20, 2018 exactly 12 weeks later I returned to the clinic for a final HIV and syphilis test both of which again were negative and also had taken the OraQuick HIV at home test also negative. The following week June 27 (13 weeks post) I got herpes in my head and tested for HSV 1/2 both negative.
At this point I'm completely satisfied with my tests except syphilis. I can't get it out of my head. This was intensified the past week when I developed a rash on the underside of my penis about 3/4" long and less than 1/4" wide, was red seemed uncomfortable but I wouldn't call it painful or overly itchy. Thinking it was fungal as I also have tinea versicolor on the entire upper half of my body I started using lotrimin on Thursday June 28 and it seems to be responding. However last night I noticed a red dot about 1/16" on the top side of the shaft near the hair area, not raised or painful and seems to have faded a bit over the last 24 hours.
After reading this can I truly forget about STDs and focus on dealing with the real issue here which was having an encounter outside of my marriage? Planned Parenthood basically told me to move on and stop testing myself. The windows that I have tested in should be conclusive irregardless of symptoms or perceived symptoms at this point?
