“Ive seen the surgery first hand. They open the penis, remove the contents, they poke the mess up into the abdomen turning the outie into an innie.”
Any chance Nikki was a hermaphodite? He/she has remarkably fine bone structure and the hands seem feminine. Can’t make out the hips, but is it possible this was more a sex assignment rather than a sex change?
Hard to tell without looking under the hood.
