We have this same, basic, social problem, at the 4th of July, County Fairs, and different, outdoor events, in the heat of summer. Firstly, the law is redundant and futile, when you already allow clothing choices, which reveal the external genitalia, in fine detail. Rude, but factual.
I am actually more of a hebephile, but most of the spring chickens will also be sloppy. If I am not attracted to you, it's like seeing the private parts on a zoo animal. I don't judge the zoo animal, for it's social nudity. It serves a legitimate, biological function. I just want no part of it. I can be passive, in respect to your body parts.
But, somewhere, it has been determined, in advance, that I have no tastes or self control. She is automatically valuable, with or without any contributions on her part, and I am supposed to lose my mind for her, on every possible occasion.
I dislike this, for the same reason I dislike some foods, musics, and colors of things, not because of the social stigma. It's like the plumber's butt, which he needs, and I don't need. We know it's down there. Does he deserve special attention for that, or would it make him seem ridiculous.
As a man, I think there is some utility in naturism, when it gets especially hot. I doesn't take long, before I remember the protective function of clothes, thankfully, with my pants on. Does she actually have do anything constructive, like chores, and can she do them comfortably, in the nude.
Or, does she just want you to look at her, all of her mileage, and water under the bridge.
