TMI - Vagina Question

tuff1june

Has anyone experienced a minor swelling of the vaginal muscle, closest to the uterus.  It's almost sticking out just a little bit, and almost feels as if the opening of the vagina is a little smaller, does this make sense to anyone or does it sound like something else someone has experienced?  I'm not in pain or anything, it's just something I noticed after going to the bathroom.
