first time

My long time boyfriend and i have tried to have sex. We've been waiting since it's my first time, but he hasn't been able to get inside me. He's always told me I'm really tight, and he's a little above average size. It just hurts like he's ripping me apart every time and I can't handle the pain. He's pretty good at turning me on so we always try foreplay and he eats me out a little first, but it's still too painful. Do any of you ladies have some advice? Should I take pain pills or alcohol first or something?
