Most girls above HB6 do that as a matter of course @voider, because I must sadly report that many a modern male is quite a bit too damn thirsty for their own good. Never go for "the home run" ASAP. Hell, there's a reason Casanova was so damn successful in his escapades. For he regarded the mere act of speaking with an HB10 to be the equivalent of... y'know, that.
I am curious as to what "culture" you consider yourself belonging to. I am a "man of the west" but I've done my homework on more than a few. The gathering of research data, pretty sure I'm not the only ILI who can't resist the urge to collect it at every opportunity .
