According to a book I read recently, the old adage about having to do it by date number three is still in effect. In "Dating Makes You Want to Die (But You Have to Do It Anyway," by Daniel Holloway and Dorothy Robinson, the authors suggest, however jokingly, that a sex-free third date will make a guy think, "Crappo. A prude. I am out of here."

I'd thought this an outdated notion -- or at least one that only exists on TV. I don't know about you, but the past few third dates I've been on, I didn't even kiss the guy, let alone drop my pants. (Am I a prude? No, I just need to start dating people I'm actually attracted to, but that's another story altogether ... ).

But I know I'm not representative of all daters, so I'm curious as to how many actually abide by this third-date principle.

(Overall, the book did make me laugh out loud once or twice. But it's more useful as a quip-heavy, pop-culture, metaphor-filled entertainment resource than a dating guide.)

So tell me: Is the third date your go-to sex date, or do you wait a little longer? Do you have a set schedule, or do you see how things go with each guy? Attached ladies, when did you finally get busy with your guy?
