A muscular men with breasts would be very weird. Like a bearded lady. With mustache. It's the kind of thing that makes people confused since one of the very first things our unconscious (and conscious) mind wants to know about someone when we first see them, is their sex. If we can't determine or it's confusing it makes us uncomfortable and we like the person less. And we of course wouldn't be sexually attracted to them.
