How do I masterbate on my period!?
The same way you always do. You will learn with time - that masterbating by sticking things in your vagina does nothing for you.
If you want to pleasure yourself pay attention to your clit which is at the top of the vagina and is a pea sized bump. If you use tampons, you will have no problems because it's not inside the vagina.
Yeah the same way but guess I would not want to touch it if I was on.
