Help!! Sleeping over for the first time.

I need advice!! Asap!!! My boyfriend asked me to spend the night Sunday. I'm scared because I've never stood over a friends or a mans house. It's just something I grew up with. I'm 24 and yeaaaah I'm not used to getting in trouble from my parents. I love this man so much. We have had sex and my parents have met him. They haven't said anything bad about him. What do y'all suggest I do?? I'm nervous. I do want to spend the night. I just know there will be consequences though.
