Opening up a long term relationship. Advice?
I've been with my partner for over four years. We have been very committed and loving. We have been sometimes long distance as well because I attend college. Also my partner is male and I am female. He brought up the idea of becoming physically open on our relationship. I have identified as queer for a while and so the idea is that we would pursue same sex flings outside of our relationship but only physically. I've never been with anyone but him and I'm excited he suggested this. But I trepidous about having casual sex. I think this will strengthen our relationship but I'm not sure how to transition to causal sex with others without guilt, and how to even have casual sex which I thought I would never have! I want to be clear, I want this, I'm just nervous and could use some ideas/stories/advice or anything on how to strike out on this new adventure.
