Love when the panic sets in and they're hit with an "oh fuck..." moment when they realize they've fallen for a guy. My favorites are the minor crises that ensue but I fuck with them also fully embracing their newly realized orientation, too. Bonus points if they insist they're straight and then are unavoidably and aggressively turned on
Types: "I'm not gay!!! ...but..." "Huh, I guess I'm okay with guys too, huh?" "I'm not gay! (Proceeds to fantasize about men)"
