And let's start with looks. Not our physical differences, but the importance we place on how we look, and how the opposite sex looks. For guys, looks might initially attract you to a girl, but then you want to get to know the person and see if she has a good personality. Girls do just as much checking out cute guys as guys do checking out cute girls. But if they're not a good person, they become so much less attractive.
People are more attractive if they have a better personality.
Girls often feel pressure to look good all the time. That's like every message we girls get. As a Christian, I know it shouldn't make any difference how I look, because beauty is fleeting. It's what's on the inside that counts. But it seems like girls just have to impress people with their looks more.
