Pain in mons pubis after sex?

La

Is it because “overuse”? What can I do to relieve the pain? It hurt when I touch it, I had dex for hours after a year without it and I think the thrust of my clitoris in his pubis hurt me. It feels like when you exercise a muscle but is it the bone? Is there a muscle there? Is on top of my clitoris. How can I relieve it?
