<s>[INST] Hello doctor, I had anal sex and now my butt has been hurting all day for six days now. And every time I have to poop or wipe it, it is very painful. It is very uncomfortable when I sit or lay on my butt. [/INST] Hello. There might be a small tear in the anal region, which is commonly called as an anal fissure. Even a small fissure can be really painful as it causes a spasm of the anal opening. It heals slowly, as it gets irritated repeatedly during the bowel movement. You might even notice blood on the toilet paper or in the stools. I suggest you get examined by a physician. Warm water sitz bath, which involves sitting in a tub warm of water, to soak the painful anal area, helps a lot in this condition. The other recommendation is to take a high fiber diet. Your physician, after an examination, can prescribe you analgesics and a stool softener. Hold off on more anal sex until you recover from the current problem. Hope your query is answered. Best wishes. For more information consult an HIV/AIDS specialist online --> </s>
