Good point

There was the guy who was perfect in many ways, loved the right music, voted for the right person, said the most wonderful things when I most needed to hear them, and (and!) he was an amazing kisser. It was just all the stuff that happened after the kissing that made the relationship more and more difficult to rationalize, and here is where I experience a lot of hand-wringing for all my Mormon girlfriends who got married without ever having slept with their men. It's admirable, very admirable to enter into the covenant of marriage as a virgin, but what if smack dab in the middle of that first-night passion he starts quoting Al Pacino in Scarface? Or starts yodeling? Or says, "Do you mind if I turn on some Yanni?" IT COULD TOTALLY HAPPEN. This is indispensable research you have to conduct, or else you're going to spend the rest of your life faking headaches. [emphasis mine]
