Anal pleasure

In some point of my life I felt curious to stick something in there, I started with fingers, it was painful at first, I kept trying until the fingers weren't enough and I started using other objects until I got to fruits of good size. I never considered myself addicted, I did it very little, but everything changed when I started being attracted to trans girls, it took a lot of time contemplating and searching for a way to have an encounter, finally it was possible, but I wanted something interactive, but she only dominated me and it's not that I'm complaining, having someone suck my cock and get penetrated by someone for the first time was another world. But having to receive pleasure every time I had the urge would be very expensive so I decided to buy my first dildo, a black one of 18cm, it was very good, then I bought a series of plugs in three different sizes, always getting to the last one was difficult and more tasty, over time I felt more experienced and decided to buy a bigger dildo and oh boy did I find the right one, it's 20 cm long and 4.5 cm thick, it's the most tasty, its texture is very smooth, with an ideal size for my needs, although I've never ejaculated from anal stimulation, I passed the time deliciously, my last acquisition was a vibrating plug, I'm still not used to it but I want to keep increasing my collection, even going up to a thicker dildo. In short, if you stimulate yourselves anally what do you like using or what do you recommend for increasing pleasure?
