Struggling to penetrate, need help /u/wisdom_teeth_313 Sex

I am 21F and my boyfriend is as the same age as me. We have been together for almost three years and our problem is that we have never actually had penetration sex before. I feel like my vag was too small for him to get in and his dick is about average size (about 4-5 inches i’m not so sure but sure ain’t a problem to me). Like everytime he tried to get inside me it was blocked by the boney part right at the entrance. And it hurts like hell everytime he tries to put more than 1 finger inside me although I remained relaxed at first and was turned on. The thing is that this has never happened to me before when i was with my ex. Is there any way that I could loosen my part or is there a position that makes it easier for penetration ? Or maybe I had an underlying medical issues that makes down there tighter than normally ?
