Besides a huge cock I have plenty to offer....
I don't play games, I don't lie, I hate cheaters, I pay for dates, I am nice and respectfull, I have a decent career, I own my own home, I am STD free, I would say I am great at sex but that would be a lie, I work out and groom well, I like seeing the girl I'm with happy, etc.
The more I do the above things the quicker they lose interest it seems. Being the guy mentioned above apparently becomes "boring". Thus why I will never be that nice guy again.
