If you remember old craigslist, you’ll know that it was once the seedy underbelly of the internet where nothing was off-limits. It was a shameless and wild playground for deviants like me chasing after things we’d never admit to in polite company. If you had the patience to sift through the BS, you could find whatever your twisted little heart desired.

One particular w4m post caught my eye and it went something like this:

Looking for a “sexercise” partner

Exercise isn’t my thing, but combining it with something I do love, sex, might just do the trick. Let’s burn calories, have fun, and get our hearts racing together. Open-minded and ready to sweat? Let’s connect!

I wrote a thoughtful and genuine reply, the kind that might stand out in a crowded inbox full of “hey” and “still looking?” messages. I made the cut, and we quickly exchanged photos. We both passed the “I’d fuck that” test, and that’s how I met Cory.

Cory was pure Midwest. Blonde, big-boned, with a little extra to hold on to. She worked in fashion and dressed in a way that celebrated her curves rather than hiding them. She carried herself with confidence, and that was sexy. We set a date, and I picked the spot, a dimly lit vodka bar where we had to sit too close to each other. Drinks turned into flirting, and flirting turned into a cab ride back to my place. That’s where we got serious about doing naked cardio.

We started with some good old-fashioned missionary to warm up, a solid move for building endurance and working on core strength. Then we transitioned into cowgirl, giving her a good lower-body workout while I held on for the ride. We finished with doggy style, which offered a full-body stretch and the added bonus of letting her stretch and arch her back.

By the time we were done, our hearts were racing, and it felt like a successful session. The truth though? We probably drank more calories than we burned. But hey, you’ve got to start somewhere.

Cory and I kept up our sexercise routine for a few months. I’d show up at her apartment, and often, she’d greet me at the door naked, ready to work up a sweat. Sometimes I stayed the night; other times, it was just a quick “workout” before heading home after work.

Over time, it started feeling more like a relationship, something I wasn’t looking for. We eventually fizzled out. I’m not sure if either of us lost any weight, but we definitely had a hell of a lot of fun trying.
