This is actually quite an interesting thread. Made me examine myself a bit.
The simple bit: I am male, straight, monagamous.
Something my wife only made me realise quite recently: I don't make male friends easily and have none. Other men I compete with, I cannot connect with them as friends, but can work with them in teams (like in a work or sports situation).
Being in a vee with another straight male in it is stretching me because I have to have a sort of relationship with him.
