Everyone has their own tastes. Just becasue your friends might not like this girl or that girl doesn't mean you shouldn't. Screw what other people think. You've only got the one life so make the most of it else you'll regret what you didn't do that you could've done. I heard a quote a couple of months ago: "In later life you don't regret what you did but what you didn't do."

Edit:

Out of interest, are you familiar with the Chaos Theory??

And why should we feel uncomfortable about you posting pictures of girls?? Or was that directed at one person?? Either way, post the pictures. Follow the crowd and there's a nice shepherd living near me who'd love a few more sheep in his flock. Not following the crowd is what makes everyone individuals.
