Most of the time I size up until my biggest one that reaches there. The thing is that even if I use only a tiny one to slam the prostate it doesn't feel good without emptying my intestines well past the point where it's already enough to have clean fun. I need to be completely empty, then pretty much any buttstuff feels heavenly and I get orgasms easily. Otherwise it's meh, I think my butt can't change into sex mode without it. Too bad evacuating your entire abdomen is not a fun process.
