Which one to buy?

Hey! I am a gay bottom so i have a lot of experience with anal play. I also had a aneros mgx classic sole years ago but it didn’t do much for me.

I have a good relationship with my prostate. Sometimes when i orgasm with my penis i have an amazing feeling in my prostate and those are the best orgasm i experience. But i never managed to feel those wirhout touching my penis.

So i am no stranger to my anus, i know how to feel my prostate with my muscles. So which aneros do you recommend?
