Why do I tear every time I have sex!? 🤬🤬

I’ve never had this problem before with any other partners but every time my bf and I have sex my vagina tears! Ughhh and then I have to take a break for a few days to heal and then it happens all over again.

I’m lubricated enough... the bitch is like a fountain so that’s not the issue

And the bf isn’t huge just average so whyyyyyy the fuck is this happening? Anyone else having this issue?

Edit: it is a tear at the frenulum of the Labia Minora. So it’s definitely not an “inside” problem
