So I decided to go for a Thai massage and to my knowledge during the massage I was aroused and had an erection. The masseuse whispered that she can provide a special, being caught up in the moment I queried the gesture. We were both naked and she was rubbing herself and her vagina on me, during the moment I do not recall any penetration of any sort but just rubbing of genitalia, I was aroused very quickly and ejaculated. I did not touch her during the moment and cannot recall penetrating but a rub that highly aroused me. Am I prone to HIV during this act with a masseuse as this was my first time and surely probably not hers, no condoms were used as I was told that I could touch and look only whilst she massaged.
