if the cut is at the opening of the anus i couldn't imagine it being anything more than a tear from a large bowl movement. i really don't think thats an std.
if u want to post this again i wont answer it...i dont think i've been helpful so i'll stay out of the next one.
i just read in someone elses thread that they heard small cuts could be a sign of herpes, so i retract what i said u should just have the test done to determine where u stand with this
your such a lady..its probably hemroids, or if you have anal sex you could have done some damage. that doesn't sound like herpes(herpes wouldn't appear as a cut). try taking a stool softener, and put some neosporan on the cut, but only externally.
anyways i checked if there was any sores or anything, i do see a cut in the entrance of the anal but then if it was herpes it wouldnt just hurt when i take a dump, right?
