See, even with pre-flushing (which I do, I'm not a savage!) I have to assume that some of this super duper germ shit is gonna survive & find its way up my pootie hole and into my body, where it will wreak havoc & leave me wearing a robe & slippers, sipping broth, and shopping for a small dog in a few years time.
Thats just another reason to try and avoid dropping a deuce in a public restroom.
But, if I must I take a cue from the women and try to minimize exposure. Best case, there is an ass-gasket available. The piece that flops down into the bowl will prevent direct contact between my helmet and the rim of the bowl.
