Until men are required to cover up, I don't think women should have to. Imagine how many problems would be solved for breastfeeding mothers?
I probably wouldn't participate but it would be fun to watch. (I like looking at women's boobs -- shh did I say that out loud?) hugs :)
Being a lover of the Med, I got used to going topless years ago. Everyone does it and it's so commonplace that no one turns a hair. I do echo Rose's comment above though, because when my children were babies, one would often launch itself at me. Sigh! Luckily my husband has always been a "boob" man.HugsAmi
