Pain heh

So this is like really weird for me to talk about but I’m just really curious. And I can’t talk about it with my family cause they are hardcore Christians. But like I’m having pain down there during sex and it’s not like a burning pain it just feels like it’s tight and my man going in hurts. I am having a lot more sex but I mean the last three months hasn’t been like this. It’s all new. And I was wondering if it could be because I am having a lot more sex. Please help
