I don't care WHAT people think, I think it's gross and nasty for ANY woman to send pics of her fanny to ANYone, let alone some random bloke she has known for a few weeks. And then to say she doesn't care who he shows the pics to, speaks volumes about that woman.
And people saying 'some women may do this because they had bad childhoods and have low self esteem blah blah blah,' can bore right off. People who have low self esteem don't do THIS shit. 
What's more, the OP does NOT fit into any category like that; she is arrogant, she didn't get the reaction she wanted from this man (that he didn't even ASK for!) and she is annoyed about it. In addition, she doesn't give a shit who sees the pics, and the more she comes out with, the more I am rolling my eyes.

I think most women with a modicum or self-respect would not acquiesce to such a request after such a short time and most would be horrified at the prospect of an image of their private parts being passed around the office for fun, whether traceable back to them or not.
Agree totally with this. And no @AuntyElle , it is NOT 'judgemental bollocks!' Who, in their right mind, would take a photo of their fanny, and send it to some fucking bloke they barely know! FFS, what the hell is WRONG with some people here?! 
Have to say; I am beginning to doubt the validity of the OP's claims, and what she is saying, and I think she posted this for a reaction, and to cause a controversial thread.
So I am not buying anymore of what she says, and I am OUT of this thread.
