In February this year, I had oral sex twice with a guy from Japan. I swallowed his ejaculate (quite a lot) twice or thrice. Since then I have been experiencing lots of gastrointestinal issues including unexplained diarrhea, and I'm not sure if there could be anything related to that oral sex experience, for example HIV.
I'm thinking of taking a HIV test but I'm quite terrified. Could anyone please shed some light on my risk level? Thank you in advance! <3
