ménage á moi

Advance warning: this is going to be seriously tl;dr and tmi. Something's been bugging me for a week, and I've finally come to grips with my thoughts enough to post about it.

For the people who go "oh, she's on another social justice trip, move along"... Well, move along. (I'm pretty this is all of you. Has my flist no interest in serious things?) If you're embarrassed about masturbation (especially your own if you're a girl), talking about masturbation or in any way hung up on masturbation... well, this one is about you. And me, obviously.

Ooh, wait, I said the m-word. Three times! Scary. Actually, this is embarrassing me to type, and I'm kind of positive that I'm going to have to fight not to private-lock it when I'm done. Which is kind of the problem.
