"Uh, that's sick, but maybe."

"Maybe," you say. "Kinda sick idea, but maybe."

"Yeah, yeah, I know," says Josh. "You love being your Lissa self, and Michelle is kind of a bitch..."

"Josh," you say, "I was born you and I never want to go back to being you! I'm Lissa now!"

"But you were Josh, and I'm now Josh, and there's still that lingering infatuation for Michelle in your adorable pink-haired girl head! Our only chance to cure it is to try being her and knowing what she really is!"

"Or fulfill it by staying her?" you ask. "Or maybe we become twin Michelles?"

"I hope not," he says. "Look, I'm going to be dating her. I'll try to get her to doze off, maybe after sex, and zap her. I'll take the costume to you or maybe wear it myself and pay you a visit as Shelly, okay?"

"I wish you wouldn't have sex with anyone but me, Josh!" you say. "But if it's the best way..."

You and Josh kiss and enjoy the rest of your evening. But it's your last date together for a while. About two weeks later you get a visitor late one evening at your place.
