A few things:
About half of these can be gleaned from reviewing someone's profile on an online dating site or from their Facebook. Another half of the remaining ones can be determined from a very small handful of dates (assuming you don't suck at dating, that is).
Additionally, you've yet to give a good (valid) reason* as to why someone should abstain either while learning about a person, or after they've learned a decent amount (but not everything) about them.
* Valid reasons don't include "she might try to trick you into getting pregnant by claiming she's on the pill but isn't really" (because that's the kind of shit that maybe happens once or twice a year in the ghetto, but mostly just on TV) or "he might secretly have aids and won't tell you because he just wants to get laid" or any number of other fanciful scenarios. I'm talking about reasons that actually hold for two mutually consenting, responsible adults.
