First time sleepover with a guy advice

I'm having a sleepover with my crush & I'm nervous af! He and I are both in college and are of age (I'm 20, he's 21). We met in class in April & since then talk, text or FaceTime everyday so we can get to know each other. I am still a virgin & he's not but he likes the fact that I'm saving myself for the right person so I know he's not gonna try anything. Recently he asked me if he could spend a night & automatically I said yes. We both like each other & are comfortable around each other. Can I get some advice of what to do or what I should expect I'm a little nervous, plus I'm such a shy person (but for some reason he likes that😂)?
