Hello doctor, three weeks ago my friends convinced me to go with them to a brothel for the first time and i have never interacted with a prostitute before. So i went with them even though i didnt want to, unfortunately. I went into a room with the prostitute and due to my stress and shock of getting HIV or any STD's i couldnt get an erection and i was also wearing a condom. I inserted my penis in her vagina once and she wasnt wet, i took it out and then took of the condom and left because of how scared i was. The last three weeks ive been in complete shock and i had diarrhea at some points and i have also been having a growling stomach that wont stop. Please give me some good advise doctor
