Exploit? The only way to exploit a woman, in the context of this forum, is to seduce her. I've been pretty vocal in opposing male seduction. What i have proposed in this thread is not being a d ick about getting dumped, and compounding the injury, by deceiving yourself that your relationship occurred in a social vacuum.
Look, when you make a woman scream in bed, she tells all her friends. If you have whisky d ick, well, she'll tell all her friends that, too. That's just how it is. If you're a big boy about getting dumped, and don't burn down the house over it, a lot more of her friends who remembered that you made the chick who just dumped you scream in bed...well, they might be more inclined to help you get over the chick who just dumped you.
What's the cost? As far as I can tell, the only cost is controlling your emotions, and acting in your own rational self-interest, which is what men are supposed to do, anyway.
