It's a wide world

The reason I still think that the transvestic fetishism diagnosis may be valid in some cases is because of the sissy and humiliation sub-cultures which exist. Some people get sexual arousal out of being dressed as children (akin to petticoat punishment), tending towards exhibitionism or presenting as exaggerated versions of young women (a la Lolita as you might see in cosplay). There is absolutely nothing wrong with any of this provided that the person does not feel a sense of compulsion or distress. In other words, they feel they are perfectly in control of their behaviour and it does not take over their lives in which case treatment may be required if desired.

Many of us growing up may have misdiagnosed feminine feelings as compulsion particularly if any sexual feelings arose upon entering puberty which is what largely caused me to continue to deny my identity until I was able to fully comprehend what was happening.

The world of gender variance can be very wide which is why I think it's important to always go back to determine core motivation before settling on who we think we are.
