This is what happens when people are forced to repress themselves in order to fit in with what society says is acceptable.
What they want becomes bad but they still fantasize about it. So the fantasy's become twisted and perverse. If this person was allowed to be who they wanted to be they may not have gone down such a dark path. It really just makes me sad to see things like this.
Wife taught our dog to crawl.
She was trying to teach the dog to lay down and stay while she backed away with the treat. Our dog figured that if she kept her belly on the floor and crawled over to the treat it should be fine...
So my wife said "Good crawl!", and kept working on it with the dog. Now the dog crawls on command.
