There is no substitution for verbal communication. (Well, sign language counts - apologies to those who are hearing impaired.)
Besides, it's not like someone knows what's going on in a person's head for certain until they ask up-front.
Me, for example: I'm not like most men in that I have no particular favorite part of a woman's anatomy. I like to look at a woman as a whole. (And yes, this includes her personality as well.) A good analogy is how a person enjoys a symphony. Sure, sometimes you'll listen carefully for that one instrument layered in the rest of the music, but mostly you just enjoy the music as a whole. Of course, there are the "solo performances" when a woman I've taken a fancy to extenuates what she feels is her best asset, and I don't mind that in the least.
But yeah, file this one under "subtle forms of feminine toxicity" - specifically, that weird rule women have to be ambiguous about their sexual desires or else come off as being promiscuous or improper.
