I play in mine fairly often but I don’t call it my ass or asshole, I call it my pussi. I keep it cleaned out too, often. The easiest toy I have is the aneros vice, prostate massager basically. Slips right in very easily and has a setting that is probably to replicate the bumping of thrusting.
I have a plug that rims and squirms, little harder to get in if I’ve not used it kinda often. And then I have a bbc dildo that looks rather real… that thing I can feel when it passes the second muscle in my pussi. I love cumming with any of them inside me but I’ve found it makes a little hard to “fully” cum, if that makes sense to anyone.
