is my girlfriend an attention seeker?

Well she is a kind of big breasted girl to be honest. I met her at the beginning of school and overall she is a great person. Funny everything you could want and a looker. Which brings me to the fact that she tells me a lot of people want her breast pictures which i think is obscene and is not a gentlemen thing to do at all. She tells me she doesn't talk to them if they ask her it, but keeps complaining about it!!! She says she wont send them but keeps talking about it with the guys who ask them. It makes me mad that she complains that people want them but she still talks to them. WHAT DO I DO!!?!?!?!? or am i just getting jealous?!
