Well, it's more subtle than that. A male may wear shorts to be comfortable, but he's wearing a sleeveless top because he wants to show off his biceps. Sauce for the goose is sauce for the gander.
At work, I wear polo shirts because it's hot, not because I want comments on my arms.
And no, I'm not presenting an absurd example as contrast. My hobbies are strength training and jiu jitsu. I have large arms. I also know what women with large breasts must feel like, because the first few times I wore short-sleeved polo shirts to work, I could literally watch people's eyes track my arms. I understood why - I had only previously worn long sleeve shirts, and my arms are larger than most, so they stand out. And I got no comments, but I would have felt uncomfortable if I had.
