Is it possible that you are viewing this from a cultural view point that will not allow you to understand it?

Not at all. My comment clearly was primarily based on a matter of enjoying a functional life. It's much more possible that I am viewing this from an entirely personal matter of function and taste.
I just don't like the idea of having to keep up my emotional end of the bargain with several women. Doesn't pass my internal cost-to-benefit test. That's all.
