I successfully avoided them for over 6 years in Asia. I got caught short in a Petrol Station near Chumphon over Christmas, where it couldn't be avoided. I didn't know whether to bend over or squat at the time. I did the squat and it all went to plan straight down the middle.
I used my second squat toilet yesterday and i must say I enjoyed it. you could hear the fucker snap clean off. It didn't have to be pushed out in 3 goes like your average Farang toilet.
I think I'm gonna start standing on toilets from now on like the Mussies
