Hello, Im a 36 y/o male, heterosexual with only one sex partner (my wife). 8 weeks ago I regretfully went to a massage pallor and he entered his fingers into my anus until all of his hand was inside, gently thrusting a few times; I stopped him when it began to hurt. Nothing else happened (no sex, no bleeding). No other sexual encounters. I cannot recall if the massager had any cuts on his hand. For a week I felt sore which is what I m used to after I do solitary anal masturbation (rarely). But after that week I ve been feeling moderate to severe rectal pain; mostly burning pain; sometimes spasm-like pain; feeling something is stuck in the rectum; sometimes the pain radiates into my groin, testicles and upper thighs. The pain starts a while after a bowel movement and lasts the whole day, reducing in pain in the late evening and starting again next morning with the next BM. This was since 7 weeks; there were days when I felt almost healed - mostly when I had soft stool BMs. However, a somewhat large stool would trigger it again. I never had any bleeding nor discharge; light diarrhea is also painful. Defecation itself hurts a little, but after an hour it starts to burn the whole day. A GP did a digital exam and found nothing. A GI doctor did proctoscopy up to the descending colon and found nothing (I was feeling OK that day I must say). Said it could be a fissure that heals and recurs. Well now to the question. I m worried that I got an STD from this act. What worries me in particular is that the radiating stinging pain into the groin area/thigh is not typical of fissures, but could be herpes (from my own internet research). Burning pain is predominant though. Do my symptoms sound like early herpes proctitis? Should I test for STDs? Could proctoscopy examination show nothing, while an STD infection could still be there and cause symptoms? I appreciate your answers and insight into how to continue dealing with this if it doesn t resolve.

Hi and welcome to Chat Doctor. Thank you for your query. I am Chat Doctor, I understand your concerns and I will try to help you as much as I can. It may still be std even if rectal examination was fine. You should have tested for herpes and HPV and also do colonoscopy to reevaluate possible rectal polyps or hemorrhoids.
