so spotting after sex

Ta
How often does it happen to you guys or if it's even happened? I had some pretty rough sex last night and we where using a we vibe couples vibrator and I felt it rub pretty hard in a few places so I'm assuming my vagina is just raw and kinda torn up but idk lol I guess I just wanna make sure I'm not the only one who's gotten like this?
