Where can I find wording for creating a sexy invite for an adult holiday party?

I'm inviting mostly couples and a few select singles for cocktails at my home. With that said, I want the gift exchange to include romantic gifts ranging from $10-15. How do I word it without it sounding like a swinger party?! I want it to be sexy but classy.

Bring a Secret Santa gift for less than $15. Let's have a little fun and try to make our friends blush. (you will remain anonymous....lol)

You might want to try to work the words 'naughty but nice" into your invitation too.

Surprised you didn't get more responses. Re-ask this question and use "SEXY holiday invitation help" as the header.

i play this game every year at my 80s parties with the gift exchange - all guests get in a circle and take turns rolling one dice- first person to roll #1 picks a prize, next to get #2 can either take a new prize or steal from someone else, and so on and so on until all the prizes are gone and everyone has a prize. if you're stealing and you already have a gift you just exchange yours for theirs. it gets really fun when everyone wants that one really cool prize, and pretty soon everyone is trying to steal it! set a time limit at the end when all the prizes are gone to keep the fun of stealing going!
