First time...

Hello, I need help... My boyfriend and I tried to have sex for the first time (I’m a virgin) but his penis is very large and I’m afraid of my vagina getting hurt.. His penis didn’t fit and also we didn’t used lube and my intimate parts are hurting now... We stopped and he asked if I was okay, and We didn’t tried anything else since... I really want to have sex.. What should I do? I'm just starting my sexual life and I don’t know anyone who I can talk about this...
