“Steve always felt that he had poor performance in bed and that made him afraid of women,” Karla claims. “In the past two years, he told me that he was gay. That put him in a really good mood for about a week.” She says a week later, he took it back and said he could never be gay. “I have absolutely no idea if he’s gay, straight or asexual.”

“In my mind, I’ve never remembered being with a guy, it was just part of the conversation,” Stephen says.
