it's just self-respect. you know, when i was 17 and trying to look up sex tips since i'd just gotten my first girlfriend and didn't want to suck in bed, i read some advice that said "how are you going to dominate a woman in bed if you can't even dominate yourself?" moreover, how are you gonna dominate anything in life like your ambitions if you can't dominate yourself? every time i deny myself an extra serving of food when i want it, say no to dessert, or get up to brush my teeth even though i just want to fall asleep, i think about that. it's just self-domination.
