Last I knew clothes were clothes, man has decided or rendered what is “female proper” and “male proper”
if he was getting a “sexual” thrill from it then maybe, but for stress relief, etc its a lot safer than medications and much cheaper.
remember there was a time that Only females had thier ears pireced here in the states…
Oh well if everything else seems fine I wouldnt worry to much about it, I admit its strange but I have seen stranger things…
Just because we feel something isnt normal does not make it a sin, have you ever worn a mans shirt,pants or coat???
just relize its clothes
