First week using aneros

Hello! Today marks one week since I got the Aneros and I am in love. Previously, I had no experience with anal pleasure at all, but now I feel like when I first discovered masturbation. I can’t resist the temptation to play with it at least twice a day. The thing is, as nice as it feels, I feel like I’m on a kind of plateau.

The first two days were nice, with feelings of tingling in the prostate, but no pleasure.
On the third day, I had the first involuntary movements and signs of pleasure.
The fourth and fifth days were really fun, with much more intense sensations that lasted for minutes, my breathing and pulse accelerated, and my dick got hard from the feeling. Now, the sensations start within minutes of inserting the Aneros, and when I’m not using it, I feel an urge to use it soon. It’s really nice and awkward at the same time.
The sixth day was very much like the ones before, but now my dick got rock hard, and at some point, I had involuntary hip thrusts. It felt like I was about to cum (high pleasure), but then the feeling subsided and started again, with no real “finale” like when you cum from traditional masturbation.
