"Why don't more guys do this?..."

[Kerry Michaels]

IMO, most all males enjoy being and feeling masculine.
They would be horrified if someone wanted them to wear any female garment
The might wear something on a rare occasion as some sort of an obvious joke, but will always make it clear that they are still 100% all male.

This may be true but it?s all down to conditioning. No one has a genetic predisposition to trousers. People are just playing the role they have been told to play.
