I apologize for my ignorance on this matter, but what is the difference between swinging and being poly? I thought they were just 2 different ways to describe the same thing?
In my opinion, swinging and open relationships are more similar than swinging and polyamory.
My interpretations: Swinging conjures up scenes of sex clubs or group swaps.
Open relationships are a primary relationship with other sex partners on the side.
Polyamory is 3+ people in committed relationships, with the emphasis being on love, versus casual dating/fucking.
I've been with my partner for 4 years, with the last 3 being open. For us, it means having a committed relationship built on a foundation of trust and honesty, that includes having sex with others. In many, many ways, it's a lot healthier than my previous monogamous relationship. Cheating doesn't exist, though breaking the rules does.We tell each other about all other partners, practice safe sex, and check in on the state of our relationship constantly.
In my experience, the discussion process we required to come to a decision allowed us to create a strong relationship. We speak honestly, we can share stories, we acknowledge that even in a committed relationship, it's natural to find other people attractive.
To be honest, I could probably have a polyamorous relationship, though my man has expressed reluctance. Frankly, I don't need one - I get all I need from him. But it's also great having friends with benefits on the nights we can't see each other.
