Looking at these questions, it appears this is going to be a monumentally boring post from me. "Not yet" on most of them. A shame, really....who wants to help out with that? *smirk*
1. If you could have monumental sex where would it be (i.e. on Lincoln's lap, the stairwell of the Statute of Liberty)?
Hm. I have to think that sex on top of Devil's Tower would be pretty incredible. (What? It's a national monument).
2. Have you ever "played" with your food (i.e. a blowjob under booth #9 at Denny's, finger banging by candlelight at Spago)?
I have fondled my partner a few times under the table at a restaurant once but haven't had the opportunities I might like to. No blowjobs under the table, regrettably.
3. Have you ever had sex in motion (i.e. the lavatory on Virgin Air, the back seat of your Chevy Suburban)?
No Mile High Club or road head yet. I've had sex in an RV, but it wasn't in motion.
4. Have you ever had sex worthy of a confessional (i.e. a stall in the church bathroom, on the desk in your boss's office)?
I've masturbated in the bathroom at my workplace before. No confessional-worthy sex, though.
5. Have you ever had sex under the stars (i.e. in the alley behind Scores Gentleman's Club, the roof of your South Beach condo)?
This is one of the ones I'd most like to fulfill -- sex under the stars on a beach or out in the Arizona desert with the stars glittering like diamond dust above.
Bonus: What's your favorite place (of all places) to have sex (i.e. The Bunny Ranch, Las Vegas)?
Wherever and whenever my partner is. That's an easy one. Cool places I'd LIKE to have sex, though, include Yellowstone National Park, Disney World, Wrigley Field, a nude beach on the Riviera, and many many more.
If you want to play too, hit up TMI Tuesday to get your questions! Or just copy from my post. That works too.
