Sex with a new guy advice?

Samantha • Life✨College Bound✨Yoga✨Nature
I've only had sex with 1 guy and now I'm with a new guy more than 2 years later and wanna have sex again. This guy's is smaller. Last guy was big and it always hurt. Idk if I will be disappointed by size or happy. And above that we've done stuff just not intercourse. I'm just nervous and worried I won't feel good. He's amazing at everything else but idk about sex
