Sounds as though it could be a fissure and/or external hemorrhoid.
Have you taken a look yet? Yep, squat over a mirror. A fissure will look like a cut in the anal folds.
An external hemorrhoid will look like a swollen vein around the anus. An internal hemorrhoid might peek through the anus.
The itching might also be a yeast type of infection...you could try a med with an antifungal in it.
You could also try tucks or something like that to clean after bms to help with some of the inflammation/irritatiob if you aren't able cleanse completely or whatever after bms.
Sitz baths could also help.
Hope you are able to get it cleared up quickly...a royal pain in the butt for sure!
