"She's like this... this..." Kurt slumped, lifting his hands like he could sculpt the memory out of the air. "When I was with the circus, there was this woman... older than me, sophisticated. She wore clothes that made her bare from here" ----under her breasts, he pointed out---- "to here" ----well below her navel, apparently. "And she would do this dance, carrying fire torches ... she ate fire, too ... when I was thirteen years old I could not take my eyes off her. She was all that I thought about. All the time."
He started to sweat when she ruffled his hair and said he was sweet. His heart thudded faster in his ribcage when she played with his tail. He got spontaneous erections all the time and was perpetually embarrassed throughout puberty.
"Tommy? Tommy is like her." Only more colorful. Less showy. "Oh, except that it turns out that she was.." He gestured, ungracefully closing a hand over the general area of his groin. "And that is that."
Kurt had an intense boyhood crush on a transsexual. In his defense, she was an extremely pretty transsexual.
