What makes you look the most male is visceral fat, to find out if you've got it, stand sideways next to a mirror and just let your stomach go, if you've got little fat, there should be little difference in your profile, if not, you'll look pregnant.
Most TS I've seen have LOTS and lots of visceral fats and should put themselves on strong exercise and dietary regime till the waist to hip ratio goes down below 0.8.
My opinion is that unless your over 45, were having a belly, makes you blend with the post-menauposal women which also have non gynoid fat distribution, getting that fat off helps greatly in pasing.
