Sometimes nudist women, after some time practicing non-sexual social nudity, can become "desensitized" to what can still be perceived in a sexual manner by others.
One "striking" example of this with my wife, was the time a gush of wind blew off her stuff from the end table next to our lounge chairs while at the resort. She jumps up, and gets on all fours to retrieve them before they fall off the patio. She never even thought of the fact that she was basically in a "doggy-style" position, ass in the air and pussy fully exposed, in front of a "very attentive" male audience. And it wouldn't be the first or last time she'd bend over right in front of someone; and think nothing of it. While I'm seeing guys smile while looking at her lol!

No matter how many women I’d have seen naked, I would be just as attentive as those other men. A woman on all fours is so raw and sexy. The day that becomes run of the mill for me, I’m in trouble. So glad women don’t get it.
