I have lots of sex all the time, and my vagina hurts and it even hurts to sit. what is wrong?

Sex is trauma...: During sex there is a lot of friction and a small amount of trauma to the delicate tissues. If you have sex very frequently, you may not have time to recover and over time this can hurt (like a rug-burn). It can also be a sign of an infection. If you give it a rest for a few days and still have pain, you should see an Ob/Gyn and have it checked out. Best wishes!
