How to use Aneros Peridise?

Hey guys.

I just got a Peridise and a Helix Syn Trident, and I’ve had one wet ‘gasm with the trident. However, I’ve tried both sizes of the Peredise and I haven’t really had anything happen for me yet.

I left the small size one in while I slept, but nothing happened there. I had the larger sized one in for a few hours, but no feelings other than the feeling of just having something inserted.

Am I doing this wrong?
