10 years ago when my, at the time, gf and I picked up our first fuck friend.
Over 2 years ago I fell in love with a fuck friend. I realized then I could be poly as well.
I have a love hate relationship with poly. I was comfortable as a non-monogamist but poly .. well I am up and down. I had a lot of anger when I first figured it out. And whether or not I can actually be good at poly relationships, is something I always fight internally with.
There has bneen talk of poly/non-monogamy fitting on a sliding scale range. From "ya I can do non-monogamy" to "holy crap monogamy is for the birds"...
Can you exist in a relationship where you are with one person for the rest of your life knowing you "can" be with others. Thats up to you.
