I'm not sure if I'm having sex right...

The two times my boyfriend and I tried to have sex I couldn't tell if it was right... it hurt so fucking much and it didn't seem like he went in very much. We do other stuff but for some reason we can't do this. I've never used a tampon I don't know if that has anything to do with anything but it just really sucks and I feel like there's something wrong with me...
