HELP...muscle quiver after masturbating

Soo like 2 weeks ago I masturbated like 3 times in one day (which I’ve done before) and this time I noticed a muscle quiver on the right side, on the outer labia kinda. The quiver feels like the feeling you get when you shiver from being cold. Anyways it isn’t constant and usually only happens when I move or am contracting that muscle. My question is when will it go away?? Or how to help it go away? Has anyone had this before? It’s soooo annoying!!!
