Since coming out as a cross dresser my underwear drawer is now void of male underwear. One side is for my different styles and colored panties and the other side for my growing inventory of colored bras.
I am completely comfortable dressing as a male when I have to but if there is a chance I might have to remove my clothes ie: Doctors then I wear black or white cotton panties.
When I am in the privacy of my house probably 60/40 female and at times much higher percentage. I feel much more comfortable dressed female because it makes me feel that more at ease as female.
I will always be male and no way Trans as it is too late in life. 50 years younger now might have been a different story because of the changing outlook on life styles now.
