Nature is universally flexible - so following that thought I've always considered that thete are two genders. But in my opinion there is everything out there by degrees from the the total Alpha male (he man) to the Alpha female (she woman) with all the connotations of each stereotype. The dilutation of the "Alpha's" into the centre ground that sits equi-distant from both "Alpha's" really don't know which way to turn - so to speak.

And there's everything in between.

The myriad of personalities across this wide spectrum varies accordingly - as does the characteristics and ***ual preferences.

The reasonably new ***ual variation that's been recognised are the 'A***ual's' that have literally no interest in either ***.

The adoption of kids to same *** couples is now accepted but I'm with Chubby Brown - it used to be Adam and Eve NOT Adam and f#@$#n Steve.
