I have swelling in my vagina. After sex. It's a pinkish-red ball sticking out. No latex allergy. Not cliteris. What is this? Normal? Will it go away?

Vaginal cyst. A pinkish red ball like structure that sticks out of the vagina particularly after sex could be a vaginal cyst that increases in size due to the increased blood flow that takes place during such activity. The best way to have it evaluated by a gynecologist.
