There shouldnt be any motivation behind buying a gift, execpt to make that persons life a little better, or feel better. If your doing it to get sex, or for any other reason, you are selfish, and supplicating. If you dont give a gift because you dont want to seem AFC, you are STILL selfish, and supplicating, only this way, you have saved yourself a few bucks, and your overall value goes down a lot more than if you gave her a gift out of supplication. With either form of supplication, you're still doing it to gain or keep interest level/attraction, which makes you an AFC. If you dont buy her a gift, you are now a cheap afc.
If you're not buying her a gift, do it because you are a cheap-o, not because Roissy said so, or you think it would be putting her on a pedestal. At least you'd be honest, and non-supplicating.
And dont think she wont tell EVERY one of her friends that your a cheap fvck. That shyt gets around and will blow you out of other opportunities, not to mention all her friends will probably try to get her to cheap on you cuz she deserves better than a cheap ass piece of shyt.
How about just buying a gift for the same reason you would buy your friends or family gifts?
I'd hate to see the kind of girls that would stick with a guy like that. They would be too boring and submissive, and low self esteem for me. Some (insecure) guys like that though. I like girls with personalities and healthy brains, personally. I want a GF not a slave.
