Personally I've always wondered given the importance of genes and hormonal responsiveness to testosterone and oestrogen for behavioural traits, would a very masculine gender flipped guy be an extremely extremely feminine girl or still very masculine, would an already very effeminate guy be a more feminine girl or a more masculine girl?
The average gender flipped character is usually already quite effeminate as a guy which makes me think the idea is a little underexplored, but what if it's some hulking confident alpha male type guy would he just become some hulking very aggressive masculine woman or an extremely curvy, caring and maternal feminine woman?
