thank you so much for your reply!
Welcome to the Forum. I will try to help. Your risk of infection from the exposures you describe is zero. You o not have a medical reason to seek testing and certainly do not have any reason to expose yourself to the risks of PEP. Here are the facts:
1. You had protected anal sex and mutual masturbation. Both condom protected sex and mutual masturbation are safe sex, despite the fact that it is typical to get each other's genital secretions on one another during these activities.
2. Surface contamination of skin with HIV infected secretions does not lead to infection .
3. Even though rates of HIV may be higher among Thai commercial sex workers, most still do not have HIV.
4. Differences in infectivity among different strains of HIV make only a very small difference of risk and in your situation where there was no risk to start with, are irrelevant.
Finally, your concerns, like those of many who visit this site, provides a great example of the power of the internet not only to inform but also to mislead. While there is much useful information available on the internet, much of it is also taken out of context or a bit unbalanced and some of it is just plain wrong. Please do not use the internet as your source of infomration
Putting all of these facts together, as I said, you have no reason for concern, testing or PEP. Take care. EWH
