I had protected vaginal sex with a girl once who told me she had contracted genital HSV1 from a boyfriend. I did have unprotected oral sex, but I don't recall seeing any cold sores. My concern is that she was a bit on the dry side so the condom kept sliding up, I kept readjusting it but there is a possibility some fluid touched the skin of my penis.
Is this a high risk encounter? Also, how effective are condoms at preventing infection?
