Beauty only exists where we view and appreciate it. The same goes for ugliness.And everything's relative.
I don't follow the belief that 'real women have curves', because that creates as much of a complex in skinnier girls as fashion magazines, etc give to 'larger' women. I like what I like, and that goes for both genders. I like my guys wiry or cuddly, and gals with tiny bewbs and ones with hips. As long as they're healthy and happy with their body, then so am I. Beauty is beauty. And appreciation of beauty is different to attraction. Sometimes people say someone's ugly just because there isn't that immediate attraction, though said person may be quite beautiful.
On the whole skinnier girls complex, I was a lot hippier with more boobage about a year or two ago and was quite happy that way. Due to personal shizz, I've lost quite a lot of weight (and boobs... sniffle...) so I really don't buy in to the image of what a "real woman" looks like.
Okay, I may have rambled but was hopefully on topic...
