Oh, am I the 'first' to answer this? Wow, this question begs for stereotypical answers doesn't it? LOL
Let me focus first on the term, 'nesting'. In my opinion this is most frequently used when a woman is preparing her home (nest) to receive a baby. The nursery is prepared...the home is prepared...and the woman is preparing her own body-settling in.
Now, if you are referencing this term in a different connotation, such as being a homebody or being a person who hones in on transferring the 'house' into a 'home' with wonderful aesthetic touches that create an ambience...that is a different type of nesting.
In that situation-either male or female can create the ambience best suited for their individual style. I've observed homes of (male) dentists, architechs, engineers, and nurses and female police dispatchers, nurses, dentists and engineers. They are all very individualized, and all are transformations of their personalitites-not necessarily their sex.
:) How about your ideas?
