@Tygervibrations alone never really did it for me - I doubt the satisfyer would work. And I feel like it still need to be maintained in place somehow (I know, first world problem here.)
Your analysis of the o-matic toys are convincing and I just might treat myself. I’ll wait a few days, trying to find more reviews, but I’m pretty sure I’ll order it on my next paycheck. Worst case scenario, I’ll use it manually, which would be a shame, but still, I’m pretty sure I can make it work.
I’m still open to other suggestions. I’ll keep a look on this post and update with my comments if I really get it (shipping tends to take a few weeks here, so don’t hold your breath for it - it probably won’t be before April, even if I order soon)
