What function did Jonathan choose and who gets changed?

Jonathan Makes Dave and the Girl Transsexual

Jonathan had chosen the SEXUAL ASPECTS function, specifying TRANSSEXUAL. So when he zapped both Dave and the girl he was in bed with, they both became confused and a little disturbed.

Dave looked down at his body and felt uncomfortable with it. He never felt like this before, but right now, he had this overwhelming desire to change his sex. More than anything, he wanted to be a woman. It was weird and totally out of place with his memories, but he couldn't deny that the idea of being a woman appealed to him. He was already thinking of taking up the act of crossdressing.

The girl, whose name was Amber, felt equally uncomfortable. She never felt like this before, but right now, she had this overwhelming desire to change her sex. More than anything, she wanted to be a man. It was weird and totally out of place with her memories, but she couldn't deny that the idea of being a man appealed to her. She was already thinking of making a doctor's appointment to have breast reduction surgery to hopefully make herself flat-chested.
