Before reading my question, kindly head back to my previous question as the encounter this time was with the same guy.

So another day at the massage center with the same gay man.

While i try my best to do everything protected, this time i don’t know how he ended up being behind me in a doggy style position and inserting his penis between my legs without condom. I am 90% he didn’t penetrate but i believe he was close enough to anus and might touched it and kept moving back and forth. Then, we swapped the positions and i came behind him doing the same thing but between his legs.

I keep asking myself, what if, what if, what if? So please i really need your advice regarding what is my risk here regarding all STDs, STIs and especially HIV before i get close to my wife.

Do i need to test for any kind? Do i need to start taking HIV PEP?  

Many thanks for your cooperation.
