Aneros does not move much

Don't worry about it, you don't need a lot of movement. When the time is right, it'll move. Just focus on the feelings of pleasure and it'll lead you there. We have a lot of left-over assumptions from traditional masturbation... and I think the idea here is that long, stroking movements will initiate the pleasure. But the relationship isn't that simple. I've had powerful "auto-fuck" contractions that didn't produce any pleasure at all, and eye-rolling orgasms that were accompanied by only a very small twitch.
Don't get hung up on the movement. Big contractions might pay you a visit, but they'll feel right and a natural part of what ever else is going on.
