If you’ve ever watched Jerry Springer a LOT of the trannies he had on there actually got their kicks out of fooling heterosexual men by not telling them what they were. It was sickening to watch them ‘reveal’ and gloat about it.
A former Navy Electrician’s Mate I worked with told me about an incident during shore leave in San Francisco.
He and some shipmates were drinking in a bar. One of the guys was getting friendly with a tall blonde but suddenly he froze and stopped talking.
The sailor next to him noticed and asked what’s wrong?
His whispered reply was, “She’s got a hard-on...”
Hilarity ensued then and there, and also later aboard ship when the story went around.
