This both makes me sad and pisses me off. It's such a manifestation of patriarchal heteronormative values. I'm super into my husband. I love him like crazy - and I'm also bisexual although I really like threesomes. Nobody needs to feel sorry for me - or for him. We're happy, and have a healthier stronger relationship than most monogamous people I know. It's so past time for more people to open up to other relationship styles as valid and enriching - and to MTOB if it isn't their particular thing.
