If you had unprotected vaginal/anal penetration ((the minor penetration you described before)) you should get tested. The risk is low, however, you should refrain form unprotected intercourse until you get a conclusive result at 3 months post exposure.
It was practically just the head that entered (if that) due to her rubbing my half flaccid penis on her vagina, I don't recall being fully inside as I was not hard enough. Can you elaborate on the symptoms I described at all. It would give me peace of mind if you dove into that
Thank you for your response though. How do you go about getting tested? Are their relatively easy ways?
If you penetrated ((full penetration or not)), you need to get tested. Take a DUO at 28 days post exposure ((no later)) as a good indication. Follow up at 3 months post exposure with another antibody test for a conclusive result.
