I keep seeing people talking about sexual games on steam. I've yet to see one. I'm sure they exist .. but how common are they? Do people actually play those? Even if I wanted to do so, I would instantly assume because it's on steam there's a chance my friends could see me playing it no matter my settings, and that would be a no-go. It's just awkward.

It'd be like jerking off with the shades open because "well no one is supposed to be in my backyard". Okay but what if some kids are there to get their ball or something? You have to assume unexpected things will happen in life.
