My husband and I are also working hard to make our relationships non-hierarchical, but since we have been together for over a decade and have built a life together and share future plans it's hard for it not to feel like he is my primary partner. My husband and I both have second partners. And we never want them to feel secondary. Because we know that we wouldn't want to feel that way. It's a balancing act for sure. The point is, I'm not super interested in hierarchy.
I am interested in lots of different types of relationships. I'm interested in allowing relationships to progress as they will (or won't).
*I have to say I have disabled my profile many, many times due to creepy, overtly sexual messages from douchebags. Calling me a slut or any other such name will incur extreme wrath. PLEASE DON'T MAKE ME DELETE MY PROFILE AGAIN.
