@sneedsam79,
Hey, you do whatever you want to.
I'm married for over 2 decades so it's been a long time since I had a first reveal with anyone. Can't say I wouldn't chuckle or make jokes if I saw panties the first time I was about to do the horizontal two-step with someone. Then again, if they were nicer'n mine, I might be a lil jealous.
Personally, I go with cotton as it breathes better.
And the fact that undergarments are supposed to breathe is kind of amusing in and of itself.
But hey, enjoy. But don't be surprised if first reveal is awkward as hell.
