ken, i know a LOT of bodybuilders who aren't even close to what you are describing. the men i know who demand physical perfection are mostly the toned guys - not the bodybuilders.
i used to be a bodybuilder - and there aren't many women bodybuilders out there. i started by working out, then fell madly in LOVE with free weights, leg presses, hack squats, and so on. i was able to get big not because i wanted to show off, but because i LOVED working out. and at a certain point, because of that love, i became devoted to developing size - a passionate hobby.
i have been working with bodybuilders for a while now, and i used to talk to the men i'd see all the time at the gym. i'm sure there are guys out there like you describe, but i've never met one - and i was a total gym rat for years. during a several year period, i simultaneously had memberships in beverly hills health and fitness, nautilus plus and bally's, and i knew plenty of guys at all of them.
it takes dedication to spend 3 hours or more in a gym 5 times a week. if all a guy cared about was attracting hot guys, he would spend 2 hours three times a week, and he'd do great. men - and women - who spend 15 - 25 or more hours a week have to have more motivation - or they'd get bored. you're talking about very self-centered people in your posts, and i've never noticed that wholly self-centered people HAVE that kind of dedication.
by the way, if a guy finds muscles so attractive that he is willing to spend 100 hours a month building his, it might make sense he finds muscles attractive in others. after all, dzinerbear and xtr8guy find hairiness attractive in the exact same way - and you find that reasonable.
