Hello, I recently found a small lesion on the left edge of my girlfriend's perineum. It is very shallow and perhaps 1/8" wide and 1/4" long. I believe it was smaller two weeks ago. She says it doesn't itch and it is painful when she wipes the area, which is how she discovered it. She traveled to Asia in January. I'm positive she has had no other partners but me, but last October, I had condom protected intercourse with an Asian female massage worker as well as a caucasian CSW I found on backpage (my girlfriend is unaware of this). Subsequent to those encounters I did three separate sti screens for chlamydia, gonorrhea, syphilis, hiv, hep, and hsv1/2, at 2 weeks, 6 weeks and 10 weeks and they all came back negative, except for hsv1, which I already knew I had. I have been regularly checking myself since the encounters and have never found any lesions - even to the point of seeing an STD nurse and a Urologist to verify that things I saw were not lesions. My wife and I are of european descent.
I have urged her to see a doctor, and she plans to do so but hasn't yet. Her delay is driving me crazy since I don't believe that I could have given her this, but don't know how else she would have gotten it.
So - the question is, is there any possibility that I may have picked something up, not had symptoms, but passed it on to her?
Thank you for your help and for the forum.
