Ah, the whole 'alpha male' thing - the staple of all amateur psychology. In most animal groups, 'alpha' just means leader -- an animal with leadership potential who is waiting for the current alpha to die/retire will actually be a 'beta' in most animal groupings. The concept makes sense when you're dealing with groups of 10-100, but in cities of millions and global communication linking us to billions, the concept sort of falls apart.
The idea of a woman submitting herself sexually is a big turn-on for me, so I can totally understand guys who are in to fake tits for that reason. In my eyes, unless a woman is really confident and assertive in her daily life (which implants seem to contraindicate), dominating her sexually just isn't very interesting. I guess I like the sense of accomplishment in having a smart, sexy, confident, aggressive woman bound + gagged while a spank her ass.
