So me and my boyfriend have been having sex since the end of last year, never had any problems. But about a month or so ago, my boyfriend came over and we ended up having sex like six or seven times in the same day, afterwards I was the tiniest bit sore.

The next time we had sex I had this awful pain in my vagina when he put it in. He investigated a little bit with his fingers and said he felt some sort of rub or something like a graze. Ever since then sex had been a little painful. Any ideas what it could be? What might be the cause? (I've heard of women having sex with their male partners almost 11-12 times a day, I don't know how they do it)
