No, lucie. I am perfectly happy swimming in the nude too. And with communal showers, and with my body.
I don't suppose I was ever as gorgeous as RRW, but I am now size 12, 34E breasts, quite happy with my figure. And when I was a slim little 20 year old I happily wandered around student lettings semi-clad en route to the shower, just like everyone else.
What I dislike here isn't the nudity, obviously. It's the fact that these women
a) Have to raise money for the troops, because the government got into a stupid war they now aren't funding properly, and
b) Are posing in positions that suggest they're being threatened and/or decorating war paraphernalia and, explicitly (this being a nude calendar) associating these things with sexuality. I don't find being threatened by an Alsatian sexy; I don't think it should be portrayed as sexy. Given that there is a (doubtless non-deliberate, just ignorant) parallel with Nazi atrocities, I don't see how anyone could continue to defend this.
