Is monogamy natural?

chefbethrogers:
I don't think it's a question if natural or unnatural.  It's a question of what works for you and your partner(s).  Remember that love does not decrease by being shared.

I agree.  I'm part of a swingers couple.   Very open sexually and our relationship is thriving. Infidelity is not a problem in my world, which is awesome
