Normally I'm celibate but recently got back into a relationship and now we're sexually active. We don't have sex very often (due to living circumstances-both still at home with parents). However, the last time we finished having sex I noticed the opening of my vagina felt as though it was burning; it was really sore and we couldn't have sex for a couple of hours because it was too painful. I tried to put it down to the fact that maybe my body's not used to all the sexual activities now going onor maybe he was a bit rough but it didn't hurt when we previously had sex. i've just started the pill too, and on that occasion it was our first time without having to use a condom. I'm not really sure what to think. It went once we had sex a couple of hours later but I don't want to keep going through this each time we have sex as its worrying...any ideas on what it is and how to prevent it from happening again???
