Mushrooms developing on, in, or around the anal regions, especially in the crack, resulting from not cleaning the anal cavities and not cleaning the semen from your anus after homoerotic intercourse.
I haven't showered since that homoerotic experience and there is a certain very exotic fungus developing in my rectum or anus region. I think it's cragmag.
