Comments like those are the real reason of why she is in the UFC.
Funny thing is that when she was not that famous, she was saying things like "I will never pose nude because of what my future children would think". And look at her now. Already posed naked for ESPN, talks all the time about how much she loves sex, and I bet that in 2013 or 2014 she will pose for Playboy.

She is a great fighter, kinda shame that she has to portray the image of a whore.
But that is unfortunately how the world works. If Gina Carano (who is 100x more beautiful than Rousey) made comments about sex, she would have been in the UFC 3 years ago.
