See, that's the thing that gets me...the guys who are being judgemental and not very nice about bigger girls aren't exactly prize winners thamselves. I'd guess about 70% of them (that I've seen doing it) either have beer guts, are overweight, balding with a comb-over, bad breath, BO, fart and scratch their nuts in public...or if you're really unlucky, all of the above. I'm listening to their conversations, thinking 'who the fuck are you to talk, dude? Taken a look in the mirror lately? Cos you aint no beauty queen yourself...'
There isn't as much pressure for dudes to look decent. The concensus is that you are who/what you are, and short of working out there's not much you can do about it. Unless you want to go metrosexual and get made fun of, that is. There are magazines like GQ and Mens Health, sure...but compare the amount of crap women get bombarded with daily to the amount men are subjected to.....there's just no comparison.
