I mean I really wouldnt worry about it.
It could just be that your sore. I really would worry about it.
it is possible that your soreness could be caused by friction from having sex 3 times in one day. Have you been with him before? If not then his size may also be part of the reason you are sore. If the soreness persists, you may want to call your dr and get checked out to make sure everything is ok.
