100%, discovering butt stuffing was a life changing moment for me. Though be very aware sex toy materials in the US aren’t regulated, it’s perfectly legal to sell you a toy that will give you ass cancer. If it says for novelty use only or something similar, listen to it. Look for platinum cure or medical grade silicone, glass, or stainless steel. Avoid TPE and PVC at all costs. Lube wise, get xLube/kLube powder and make it yourself, WAY more cost effective than buying it already in liquid form and it won’t have any irritants, like glycol, which many water based lubes include that actually acts as a laxative when in your ass, making for a much less pleasant experience. If you’re looking for something longer lasting or for shower use, coconut oil is also good. Still pretty easy to clean up but is a lot more water resistant and doesn’t really dry out. It does stain a bit though, so keep that in mind.

doing that does get me suppressing moans

It’s crazy to me that some men haven’t shoved things in their ass. Like half of male sexual pleasure is up your butt.

I’m on that level and still don’t really feel the impulse to make sound.
