Doc I have a question. Last saturday I had sex with my boyfriend like 4 times that night with protection but he did oral without protection. Then the next day Sunday we had sex again for whole day like 2 to 3 times and everything was fine, until the night came after eating outside, he started to have stomach cramps and constipation. Then the next morning he was fine. But yesterday I got a call from him and he said he's not feeling well, his tummy aches like unbearable and his dizzy. What could be the reason of this doc? Please help, I'm worried about him
