I am to understand that among the general male public, the knowledge of how to come to the end of a first date (especially one that didn't suck) is sorely lacking. I don't think I've witnessed a literal fight-or-flight response, but an extended-dither response is pretty common.
I don't particularly think he did anything illegal until there was actually lewd behavior or money changing hands.
I think that asking a cop to actually have sex with a senator (I mean one he's not actually dating or married to) is kind of... I don't think they pay cops enough for that. Men get arrested all the time trying to pick up prostitutes (who are actually cops); giving a woman in hootchie shorts and a halter top a ride in your car isn't illegal either.
(I begin to think that if I were an undercover vice cop, I'd be totally addicted to romance novels, as an antidote to the unromantic environments they live in. Like porn stars wearing flannel jammies around the house, you know?)
