Harness Wear

I recently had the opportunity to buy a harness (which connects to a "chock" - shorts/jockstrap) and wear it to a party. It's not leather.

I really liked it and realized that I don't want to wait until vacation next year to have another opportunity to put it on. I do very little socializing in DC but wondering if there's a particular place or places where an older guy, dad bod, who looks amazing in a harness could visit!?!?!
