Using the Aneros Helix Trident for the first time today

After having a butt plug in me for thirty minutes, I was curious to know how the Aneros was, so I took out my plug and inserted the Helix.

Am I suppose to just ‘leave’ it in there? Am I suppose to do something with the handle? The way it’s designed, color cordinated, makes me feel like I must be doing something wrong.

Anyways I did get hard the first five minutes after it was inside me. I’ve watched videos of people using it and their body starts thrusting after like 20 minutes…? Is that really possible?
