Blanket humping???

I don't understand how humping a blanket could be pleasurable at all.

- Can someone please explain how and why one would do it?

- How in the world does a blanket stimulate you? Like, it's not hard or phallic, and I don't see a way it could actually go into the hole. (No, I'm not trolling, I'm just very, very confused.)

- If this does actually stimulate some people, do you ever reach orgasm doing this???

So confused!
