What Is The Treatment For Swollen And Sore Vagina During Intercourse?

When my husband tries to penetrate I tighten up and he can’t get in. It’s always left me swelling and sore. Now we are older and dryer. Is there a product that will numb me a little? Also, is there a product that is better than KY jelly? It dries up to fast. Would it be OK to use preparation H in the vagina for the swelling?
