Vaginal bleeding during sex⁉️

So, recently I have been bleeding during sex. Like a lot of blood and it gets all over my sheets. I’ve never experienced this before and I’m not on my period. There’s not a sharp pain coming from my cervix’s so I don’t know why this is happening? My boyfriend is not well endowed down below so it’s not like he’s ripping me open.. someone please help 😫❗️
