I have had a few of these in the past couple years from the male side, but I took a personal oath to stay single until I got my career together. I had some variously bad relationships that I wanted to ruminate on while I got the other parts of my life going. Also, I really don't want to get stuck in this shithole, and I take my oaths seriously so there is a lot of subconscious motivation to miss out on that shit.
"Can I eat your dad's BBQ?"

"Oh, that's a no..."
I've also had some minor flirtations at other social events, but I ain't fuckin' until 2018!
