Younger people tend to lack confidence, so they fixate on what "people in the know" tell them they're supposed to like.
Goes both ways. Some men develop unrealistic expectations based upon what they see in... let's stick with "media". Some women develop unrealistic expectations based upon what they see in romcoms.
Personally, I think building a sense of self is the way to go. Develop your mind. Find your bliss. Push yourself. Run in a marathon or donate time to a charity. Create a multi-dimensional person, rather than simply a shallow image. Confidence? That's what's sexy. Love yourself and people will follow.
Yeah like I see on the movies and TV like everywhere girls have to be skinny with big boobs and have a butt, I mean I have even thought about getting boob job because I feel mine are small and guys don't like that. I want to look perfect for guys you know but its hard to look like those models.
Media tells me men love skinny skinny girls, my life tells me men love my feminine curves, humps bumps and lady lumps :) So no, never have believed them and probably never will. If I did believe them, I'd probably feel like shit how many other girls do, but luckily I believe people in my real life and listen to the compliments I get. I'll never look like an air brushed model with pics taken in the perfect lighting, nobody will, so who cares.
