I changed my diet, became constipated and then this is whats left. It's very painful yo the touch, especially when wiping. It actually was bleeding a few times.
that looks like a hemrhoid. try soaking in a hot bath and applying a cream. it will probably go back in on its own, but you can push it back in as well.
have you had anal sex? also try taking a pic from farther away, close ups get to blurry
