Can You Marry Someone You Screw On The First Date?

So you're a swinging single and you've had a one-night stand. What's the etiquette for establishing boundaries, calling the day after and getting out without hurting feelings? So began an email dispatched to me and all eHarmony members touting a story called "Navigating the One-Night Stand," about the rules of fucking "Mr. Right For The Night." Well. The story has since disappeared from the website and the internet at large, because eHarmony doling out advice about casual sex is sort of like George W. Bush on acing an intellectual history exam, which is why I clicked on it when it was still online. "Don't stay the night," was one of the first rules. Good point! I always let the dude sleep over, and it never gets me any farther along the "Finding A Husband" route. Anyway, the eHarmony people have since renounced one-night stands entirely, labeling them "inconsistent" with "long term relationship success," and since long term relationship success is what we're all seeking here I asked myself whether I shouldn't do the same, and focus on finding a mate with an established interest in finding Ms. Right. That's right, I checked out my eHarmony "matches"!

It's always possible to fuck someone on the first date without becoming immediately repulsed by them, right?
