I don't think most of our male designers r gay (though ofcourse there r some who r) but since fashion/arts has been more of a girls area of studies, these guys are surrounded by 90% of girls around while studying these art subjects and pick up alot of their traits. Hence, end up acting or looking gay.
If i were a male, or say if some male from my family was to adopt this field i would be very happy as its a very creative and interesting field.
