You can have both but when you're handed that amount of power and options, it's hard to remain a good person.
I was just talking with my tall good-looking colleague and he's just pounding his way through women like you wouldn't believe.
And many of those girls end up lashing out at him because he just won't settle (and he's 33). So he's just breaking heart after heart.
He always has the same justifications: "I'm always clear about intentions, I always tell them upfront that it's not going to be serious, so I'm not at fault! They're the ones making up a fairy tale in their minds."
I love that guy (no homer) and it's not just because of his halo™, but at a point, he should realize that it doesn't matter if he's honest, he's going to break their hearts anyway, because I (now) believe that there's no such thing as casual sex, especially for girls, and especially when it's with Chad.
I'm no Chad but I've broken many hearts, and it's no fun for both parties, my colleague just doesn't understand why the girls end up lashing out at him, they think they all have a problem and that he's not at fault.
I guess it's easier to be moral when you have little to no options, Nietzche used to say that it's how the weak justify their failures. But conversely, if you have options, I think it's your duty to be responsible and use that "power" to sustain a long-term relationship with a girl that you find special.
This way you'll make yourself happier in the long-term, you'll make the girl you've chosen happy and most importantly, you'll stop potentially ruining all those girls for other guys who'd like to do the same. Better for you, better for her, better for everyone else.
