In Marriage I think it's so important to be 'as one' in our ideas of what is right and wrong.. what is acceptable and what's obscene.  If your Co worker is uncomfortable with her Husband belonging to a Nudest Coloney than he ought to be conciderate of her feelings and knock it off.  On the other hand, if she enjoys them too, it's a mutual pleasure they can explore together.    I think we should all do what we enjoy in life!... UNLESS it infringes on our Spouses peace of mind.
