Soo losing my virginity

Any tips to relax about losing my virginity?  I only see my guy about 1-3 days in a row every 4-6 weeks because of distance so I've basically planned the when and where but I'm known to stress over what to eat for breakfast so this is... intense.

He's older and much more experienced.  He was the first person to see me completely naked for sexual reasons, and he's made me so much more confident in myself but I still feel like an idiot when it comes to anything sexual.  I'm working on it, but sex is big. I'm worried about embarrassing myself.

Just wanted to say this as a side note-

He's not pressuring me at all, he knows how big of a decision this is for me and he's actually pushed me to really think this through before deciding. Otherwise I would've lost my virginity awhile go.
