Decent guy will be interested as he perceives her as a challenge. It's more exciting as he is not sure whether hell get her, and it's attractive if she doesnt ut put to just anybody. Really, they like to conquer, to be the winner, feel special as he's gone somewhere where not many have gone. Plus, they respect only this stuff that requires effort to get it, it;s human nature. Something somes too easily - we don't appreciate.
And if he is a common douchebag... everybody knows, he just loves to have everything on a plate, and his sorry a*s is too lazy to pursue. Well, quite understandable, when there are so many hags around who do the job from A to Z. But really, who would like to be with someone - or just give it up to someone - who is not even willing to make an essential effort to get it? Sounds well cheap, and you know this.
參考: common sense.
