i do personally find vaginas unattractive, but in the past there have just been SO MANY photos on the front page that included them, so it was just refreshing to not see it in a nude picture (and for that, i thank you)
This isn't as sexual as some people making it out to be. Yes, her arm is kind of framing her boobs a little, but honestly, she's a WOMAN. Women have boobs. Get over it. What, it's okay for men to be shirtless on DA but when a woman is shirtless it's suddenly taboo? Bitch, please. It's sexual in a sense, yes, but because her eyes are covered and she is tilting her head away from us, she's not giving us the gratification that we are even there. Plus, you can't even see her vagina. Jeesh, people. Get over yourselves. Shocked?? Put your mature filter back on. PROBLEM SOLVED.
My guess would be that the purpose of the shot, which is pretty clearly an action shot, is to highlight the play of muscle and bone under the skin in a way that creates pleasing lines, something clothing would be a hindrance to.
