X & Y

A friend once said that he had a "horizontal relationship"... i.e. the realtionship only worked in bed. I suppose that means that there are vertical relationships which only work out of bed - Platonic. These could be referred to as Y type and X type respectively.

It means that for any relationship we might express the degree of sexual content and spiritual content as a 2 dimensional ordered pair (x,y) and so the types of relationships form an area. Being multi-dimensional there is no interaction between the x and y components, rather that together they position the relationship.

X & Y are also the names of the chromosomes which determine males and females in mammals. Women are all x while men are a combination of x & y - which fits the analysis before in this blog ;-)

I suppose what we are looking for in a sexual partner is the X factor also, since the Y factor is what we find in friends.
