Is my vag okay?

leiani • I was an old user of eve but got a new phone and forgot my password , but add me ladies Ill be more than happy to be your friend and just chat. I’m 16 btw 💗

When I try having sex with my boyfriend my vag simply doesn’t want to let him in. Or if he tries harder it really really hurts. What can this be? Also, I’m not a virgin or anything it just started to happpen out of nowhere. Can y’all help me please?
