Bad boys exuding confidence, initiative and flirtatiousness, or good boys basically being nice and gentlemanly?

Yes, the second one. First look a flirtation? You have lost my response right there.

A gentleman for me, bad boys are too wannabe

I'm assuming that girls like an in between version of this.. Although I have seen girls go for bad ass gangsters over a guy with success

bad boys are afraid cuz they know what it takes to gamble and gentlemen are just naïve idealists
