How 'bout a bifauxnen or trap character whose character story focus is not entirely gender identity or romance oriented, or keeping their secret a secret oriented...?
._. <(just sayin'...)
They tend to go hand in hand, it'd be surprising if this weren't the case, but genderbendering should only have to be a small part of the character...not the entirety, and the entirety of their character goals.

How about...
-how 'bout a magical turtle whose in love with a princess after peeking on her skinny dipping?
-a sex addict and, yet, somehow, a responsible father?
-a newly turned vampire who is entirely in denial of having become a vampire, no matter what others try to do to convince them (short lived, though, they die in the sun)?
-a vampire that doesn't hunger/crave/taste blood, due to a condition carried over from when they were human?
-a vampire with actual self-control, stemming from their life as a human...either from religiously fasting often, or starving often due to poverty...and knowing what it's like to hunger, and how to deal?
-how about an emotionally damaged individual who is hard to read and understand, whose motives are literally all over the place for no frickin' reason (like Kristen Stewart as Bella Swan, or just either on a regular day)?
-how about an immortal who is entirely dead during the day, but comes to life again at nightfall, only to spend the rest of the night slowly dying till the break of day?
-how about a genie who can grant unlimited, and totally accurate 'what you want' wishes, but charges an equivalent sum of money for their service?
-how about a pin with consciousness, secretly in love with a human, but just keeps hurting them when they roll over a little too close...(cliché)?
