How tf do I get it in?

So my bf and I just started having sex and everything’s fine and dandy except we have a really hard time getting it in, if ya know what I mean. He’s really REALLY thick and I’m super tight, but he also has a significant downward curve to his penis and I don’t know if that’s part of it or what. I haven’t had sexual with a whole lot of other people, and like getting them to actually go inside was a struggle to because my vagina is so tight. Any suggestions to make it easier?
