When a girl sends a man her naked picture... he gets excited... (pun intended)...because it shows that she really likes him. It strokes his ego, and it's very useful when he's about to knock one out. Men are drawn to racy women...it's just our nature.

In the same breath, some women love the thrill of exchanging these types of pictures (or videos). And the reality is ... women have become more open about bedroom activities. Perhaps you may disagree with the statement but the astronomical sales of Fifty Shades of Grey suggests otherwise. But of course, women only read the book... or watch the movie...because they are "curious".

Curious my ass - they're living vicariously through that movie.

A few women will voluntarily send their pictures to men because they know it will turn them on, while other women will send stuff because their boyfriends asked for it. And then in some cases, some women will send it because their boyfriends demanded it. So, although she was hesitant at first... he pressured her, made her feel guilty... until she caved in.
