Hi! Sorry if that’s a stupid question. But can anal sex mess up your digestive system? Or give you diarrhea (I’m not really sure what symptoms of that are tho)

So what happened I didn’t have anal for years (and I’ve done it only few times before that) and all my life my digestive system were fine. And last December I had 4 different guys. Two of them were on New Years weekend. Right after since first days of January my digestive system was never the same. Sorry for being very detailed but: I started pooping very liquidy and color was different (sometimes green or yellow) first 2 months it was the same then it was a bit better like one day liquid another day better and over again. Another thing happened is that after I eat it could take only 20 minutes and it start hurting and I need to go to bathroom and everything comes out as very liquidy again. This was never for me before cuz my stomach was really great.

All this time I was thinking that it would heal itself but it’s been 11 months and no changes. And I’m too scared to go to a doctor what if I get something bad from that experience? Obviously I didn’t have anything sexual since then for 11 months already.

So how bad could it be? Is there anything I could try to fix it?

The only thing I tried is to by that fiber supplement. I wasn’t really consistent with that but i already finished the whole bottle of that powder and didn’t notice any difference.

Please give me ANY advice. Thanks!
