When I see comments like this it reminds me just how different I am to many people. It feels like I'm an alien trying to understand a new civilisation.

I used to have "sex" and the like, but it was only to experience certain transmitters firing in my brain. Now that I've discovered my right hand I don't have to force myself through that hell any more. Comments like this suggest there is something attractive about such acts even if you take the pleasurable transmitters away. I'm so happy, happier than I've ever been, that I don't have to interact with another human ever again.
