My boyfriend and a I have been together 4 years and we often drive into a abandoned area of town and kiss and do all that in the car. We both have conservative christian parents who firmly believe in no sex before marriage. Well, about a week ago we were in the back of the car, i️ only had a bra on and he had his boxers on, we were on top of each other and a i was on the bottom, I️ was really into the seat in his truck when my face just went red. Then i️ just get this burning sensation right by my vagina and we both look down and there was blood everywhere, including his boxers. My vagina got cut open by a seatbelt! He literally freaked out and was handing me food and clothes and anything in his car, i️ ended up in a pair of his shorts and a tee shirt and a sock stuffed down there to clot the blood. We looked insane walking into the ER. But we forgot that the ER costs money, we told them the whole story and they said they would make up one for our parents. Well 8 stitches later I️ can have full use of everything down there and I️ know know not to get hot and heavy while on a car seat.
