Welcome back to the Forum.  Thanks for continuing confidence in our service.  I'll be glad to comment.  Before I get to the specific questions however- two important generalizations- first, most commercial sex workers, including masseuses do not have HIV or other STIs and, secondly, most single encounters do not lead to infection.  Risk of course goes up with more exposures if a partner happens to be infected.  Regarding your specific questions:---

Hi Dr. Thanks for getting back to me and clarifying my concerns. Your expedient response was greatly appreciated. Between my post and your response I managed to consult with a sexual health GP clinic that partners with the main STI clinic in our city. Their professional assessment was very similar to yours and even suggested the same optional std sti testing in 7 days for peace of mind only and they expect negative test results from this encounter. They also stated as I was receiving oral from female the risk was different from giving and if it was M2M. Is that your understanding? Anyway they also stated my encounter was nil risk for HIV, low risk for most sti and like you rather uncommon from receiving oral. Surprisingly they didn’t seem to be that concerned which also helped. Her assessment and your response has alleviated most of my concerns. I’ll just be cautious over the next few days and monitor for symptoms.  Hopefully all goes well. Regards JB

Thanks for the follow-up .  I do agree that if you had received oral sex from a male the risk would be slightly higher than after receiving oral sex from a female.  Either way however, the risk is low.  ---

Hi Dr. Thanks for then update and further clarification. 

Dr. Handsfield and I have worked together for over 40 years and we never disagree on the facts we present although our verbal styles.  He agrees with all that I said.---
