Before the GenderWave hit, Jesse Howard had known for a fact he didn't like girls. As long as he could remember she'd found them weird and gross, and he'd been so glad to move to a big city with a pretty accepting atmosphere and some bars where she could meet other men who liked men.
So, as you might guess, the GenderWave was a particularly striking experience for him. His body had felt odd and itchy all over, and he'd shut herself in his bedroom and undressed to see if he had a sudden rash or something. But what he actually saw was his body start to change. It grew lither, slimmer and softer all over, her skin seeming smoother than before. Everything was smaller, and it felt deeply weird, like he was Alice after drinking the potion. He even felt his shoulders narrow and his hips widen inwards, his proportions totally different.
The weirdest and most striking changes soon set upon his chest and crotch. In a higher-pitched voice, he grunted as his nipples enlarged and his chest sprouted soft C-cup breasts. After this he looked in the mirror to work out what was happening to his lower body, and saw his balls move up inside him as his scrotum shrank inwards and started to form labial lips. And as his body started to form something deep inside it that his former balls connected to, and he felt a vaginal opening emerge between his legs, something clicked. She wasn't a man anymore. Just to affirm that, his penis shrank away rapidly until it formed a tiny nub above her new passage. She had a clitoris and vagina.
Slowly settling down from her transformation, Jessie realized something with a deep sense of certainty. She liked girls. She always had. As long as she could remember he'd found them cute and attractive, and she'd been so glad to move to a big city with a pretty accepting atmosphere and some bars where she could meet other women who liked women.
"Well, even if I'm a guy now at least I'm still gay!" she laughed to herself in her new feminine voice.
