Sorry to double post.
I dont use a dating service now. I may in the future but we (me and my fiancee) are kinda ramping up slowly. So for now I was just happy with the non relationship specific benefits of poly: not living a lie, being happy, no guilt, freedom, honesty, communication, and the occasional flirty friend. Then I bumped into an awesome chick that happens to fall under the devoulty mono umbrella.
