HELPP

Had sex with my SO last night, the actual sex wasn’t super thought but when he was fingering me he was pretty deep in there (TMI) which he admitted every time he would put his finger in, it would hurt. We finished a s I went to the bathroom and when I peed it burned and hurt I wiped and I was bleeding enough to fill up the toilet paper. It was also on the bed. It didn’t last long because an he later I peed again and nothing was there. There also wasn’t any blood in my underwear! Its weird because before the sex I was not bleeding at all so idk if he was going to rough or what??? This ever happen to anyone
