Glitter Bears

Do you know the different social networks? Sure you do. MySpace, Facebook, Tagged et cetera et cetera. It's a nice playground for research. There are two things which I don't understand and can't figure out:

1. Why do people send glittery things to each other? Glittery bears, Glittery flowers, Glittery nude people? Especially men send it to women. Do men really think women like these ugly images?????

2. Why do men send porn photo's to women? (sorry, I don't have anything against men, but I'm a woman, and this is my experience). They better can send it to each other. They get probably excited by them.
