Spending a fun night with my new guy! Tips!?

Me and my new guy are spending a night together in a hotel room for the first time and I’m nervous as hell! What are some tips you guys have for it?

We plan on showering together while high and having sex hahaha.

Should I wash my hair in the shower with him? Is that weird? I look like a drown rat with wet hair so idk! Any advice would be great 😂😂
