Help!!!! I'm in a lot of pain!!!

So me and my boyfriends have had sex 3 times but it is so painful. The first time I thought it was normal because we were both virgins and didn't really know what we were doing and I had never had anything up there. But even now it still hurts and all I feel is pressure an pain(yes I'm wet enough).  I don't know if this is a problem people experience and I'm just overreacting or if there's something wrong with me I just wanna feel something good when we have sex. Also is there any good positions that can help?
