Masturbation Musings

I could hear a woman masturbating last night. I could also hear the TV through the wall, so I blamed the first girlie moan on that, but pretty soon I could hear the bed squeaking and more sounds of self pleasure. At first, I thought I shouldn't be listening to her and that it was going to make for an awkward hello in the morning, but I quickly realized that she had no clue I could hear, so I listened with fascination to the whole thing. I really wanted to know what she was fantasizing about.

It really got me thinking about masturbation. Why do people (in general) have to hide the fact that they masturbate? Why don't we talk more openly about what gets us off and how often we do it? Why did the woman feel she needed to mask the noises she was making with the TV? Why is it that watching women masturbate is almost always appealing, but watching men masturbate is almost always unappealing?
