Butthole is huge my anus has gotten bigger over the last few days, I mean it is huge. I cannot sit down for too long or it gets bigger, help me out please.

I . I am having a difficult time trying to figure this out. Is the hole getting larger or is there more and more tissue and swelling in the anal area? Do not know if your problem with sitting is pain. The hole can get bigger due to stretching the anus (such as anal intercourse) if the area is swelling you could have hemorrhoids. If it is hot, red, painful, swollen - you might even have an infection. If it sounds like the later, would call the doctor now to get seen. If it sounds like the former and it doesn't resolve in the next few days, call your doctor, so this can be assessed. Good luck.
