Question: I have been monogamous for 5 years with the only sex partner I have ever had (my wife). I am straight and never had any other partners prior to my marriage.

6 weeks ago, for the first time outside of my marriage, I performed unprotected oral sex (fellatio and cunnilingus) with a girl I don't know in Mexico. After the encounter, she told me that she used to be a prostitute, but not anymore and she assured me that she is clean (not that I believe it). One week after the encounter, I started to feel some discomfort while peeing, the need of frequent peeing, and noticed a transparent discharge coming from the penis (I am not sure if it was an infection or just me being paranoid).

I went to and STD clinic and they gave me antibiotics for both chlamydia and gonorrhea, before they got the test results back (which came back negative). The discharge and discomfort disappeared afterwards.

Today, 6 weeks after the encounter, I am noticing a weird discoloration on my lips.

I want to add:

The oral sexual contact happened only once with this women and it was only oral (lips kissing, fellatio, and cunnilingus).

I don't feel the need to itch or it hurts.

I am including images to the question.

I am really worried, and I don't know how to get peace of mind.

What are the chance that this is a symptom for STD (e.g., Herpes)? Does it look like it?

Image 6 is the clearest. Notice the upper lip how it is different from the lower one (it is not pink, with small white dots)


The weird discoloration on my lips is more like a white pumps. They don't hurt and I don't feel them. I just see them in the mirror. They go over the entirely of my upper lip and a little bit of the corners and lower.

Thanks for your reply. I just noticed them earlier today. Do they go by themselves? Or is there a treatment? They are not painful but I want to make sure they are not associated with genatil warts or herpes.
