This is not gay since every part of his body except the dick is pure feminine. So this is my theory, traps has X chromosomes but X is covering the Y chromosome so we have a genetic mutation where everything about the trap is feminine and the male genitalia is still in place. Hormones plays a key factor in a traps body since they are responsible for the changes and body modification that gives us the bliss and blessing of a beautiful creature that we call traps.
I think @Ero-sennin it's called klinefelter syndrome.when boy with XXY chromosome are born they have higher feminine hormone so they have female body characteristics and yuuki is extreme end when it's really look like female.https://en.m.wikipedia.org/wiki/Klinefelter_syndrome
