Do you prefer polyamory or monogamy? And just because you prefer one does that mean you don't believe in the other? And why?

Polyamory, but I have nothing against those who prefer monogamy. It is all about what your comfort level is. I would say in my current relationship of 11 years we are more of a closed polyamory now and only do things together, I just don't have the desire and time to emotionally invest and really enjoy the time with my partner.
