If the crossdressing is purely for sexual reasons such as a fetish than the man is using the objects for sexual arousal and does not seek or experience transformation for other reasons and in my mind I would not think of this person as transgendered unless....

Also crossdressing could feasibly be done for aesthetic reasons much like an artist paints but this is done with clothing and the body is the canvas and I would not think of this person as transgendered unless......

Transgendered implies transformation from one place to another within the individual, it is leaving one emotional state (emotional energy) behind and going into another and than back again (possibly back again)

In my opinion for the transsexual there is not a transformation but a revelation that is transformative through being restorative so is not movement between the opposite emotional energies of the feminine and masculine that the crossdresser who is transgendered experiences (the woman within the man) but the discovery and pursuit of original but lost truth through external changes.

In my opinion to consider yourself transgendered you must experience or want to experience inner transformation by external transformation.

The seriousness of the transgendered label could cause insult or concern for those crossdressers who just do it for entertainment and not for the transformative aspects.
