theres nothing freakish about anal stimulation, it's a common form of erotic enjoyment that dates back to ancient egypt, than popularized by the romans and greeks
it's even used in medical practices for people suffering from prostate cancer, they milk their prostate, and believe it or not there is a male G spot in the anus, and the orgasms produced through stimulation of it are said to be more intense and longer lasting
not my cup of tea personally to have performed on me, but by no means is anyone a freak, I guess that's the issue with bringing mature topics to 12 year olds, freak
