Any ideas?

Was having sex with my boyfriend and its never hurt at all before but this time i was in extreme pain i had to ask him to stop and i was in agony for about an hour ( got paracetamol after about a half hour) and it slowly got better but even 5 hours after it still hurt to laugh or sneeze or even push hopes forward while walking etc. After about 3/4 of an hour of him pulling out i went up to the kitchen and fainted my bf said what happened in that time but i couldnt remember what happened for most of it. Like i said ive never experienced pain during sex before but this was extreme. Does anyone have any ideas as to why? Sorry if this is hard to understand —also bow the next morning and not to bad but the pain is still there with peeing/sneezing etc..
