This is all quite remarkable.
It used to be that whatever sexual proclivities a person would have, it was not discussed in public, and certainly not broadcast on a somewhat prominent website where such admissions will be made available to everyone (including one's children when they grow older). This is true even for less deviant matters. It is bad enough that people like Stan often talk about it while at brunch or in public, but now she has gone and done this.
One would expect this sort of revelation because another user on this forum discovered a lolcows fetlife account. But here she divulged this of her own free accord.
This is a really longwinded way of saying you think ass-eating is dirty and degrading.
I for one do not think it is, it simply is. Value judgments--society used to make them. It still does, it is just that things were once considered normal and healthy (because they are normal and healthy) are considered deviant. Example, was not long ago that overwhelming majority were against interracial relationships, as they should be. Now publicly expressing such sentiments can cause outrage, while society has normalized the entire gambit of deviant behavior.
There is something else, and
@RichardMongler touched on it. Society applies different standards to men and women precisely because men and women are different. When Lindsay Lohan or Amanda Seyfried flash their kitties, it is looked upon very differently than if a man exposes his genitals (intentionally or not).
Even today, a man who talks about his sexual proclivities is generally looked down on--think for example the sort of guy who would wear a tshirt that reads "Pussy Slayer." A man talking about or getting caught masturbating is also looked at very differently than a woman doing so, although when a woman is as unattractive as Stan it is not treated the same way as a more attractive woman.
I am completely befuddled by this behavior of broadcasting such things here, more so than the behavior in question. It is not unlike someone detailing embarrassing, weird sexual proclivities to the New York Times or People magazine, and it gets published.
