/r/polyamory and /r/NonMonogamy are great resources to learn more about non-exclusive relationships prior to entering one. It's very important that you talk this through until you are both horse in the throat.

You need to know why you are entering a non-monogomous arrangement, and you need to know if it's just about sex, or if it's ok for love and emotions to develop too.

You need to discuss whether the "other people" are going to be strangers and one night stands, Friends with benefits or fuck buddies, Or "other girlfriends" and which of these do you and your boyfriend both want.

Are you a jealous person? have you felt ok with open relationships before or is this a brand new concept? is it resonating or is it sitting uncomfortably?

I'm going to talk about my personal opinions here, so take all the following with a grain of salt.

Personally, I feel that polyamory is something you are hard-wired for, You are either a polyamorous person or a monogomous person, Like other elements of sexuality this is fluid, but it's not exactly a "choice" per say. But getting involved in a polyamorous or open relationships is a choice, and anyone can try and anyone can do it, as long as you are open, honest and communicate, But people who are polyamorous by nature will be more comfortable with greater ease.

I met a man in my mid teens and we got married in our early 20's, we were together for 8 years. At first sex was new and novel, and that made up for my lack of sexual attraction, Prior to meeting him I thought I was a lesbian or something because I'd never been attracted to men the way my friends were, But I loved this man with all my heart, so that's all you need right? a few years into our marriage I started understanding asexuality and realising I was definitely on the spectrum. I voiced this with my husband and he was always supportive, But for him, sex was a very important component of romantic intimacy. I was suffering from vulvodynia and pelvic pain due to adenomyosis, so sex was physically hard for me, coupled with a lack of attraction and all the medication I was on killing my libido, we had a pretty serious case of dead bedroom.

We soldiered on for a year, giving sad hand jobs and having sex when I could manage it. I loved him and I loved seeing him happy, but he knew I didn't have sex for the same reasons and he couldn't enjoy it knowing I wasn't on the same page, so we stopped having sex all together.

Over time, I began to become more like a best friend/sister/Mother figure than a wife, and that was fine, we made each other happy in our own unique way. But he needed more, so I brought up the idea of a open relationship, There was a girl at his work who he found attractive and I knew her too from my Uni and knew that she would be perfect for him, so I told him to go for it.

The three of us had a lot of long discussions on how it would work and what we would each mean to him, It was decided that In would be the homemaker and den mother to both of them and she would be the real wife.

We had a great year together, went on holidays, had date nights and so on, We alternated between him and me hanging out, just them hanging out and all three together. We were happy, but we knew that it would end with me leaving and them having a life together.

So I moved out, My husband visited every other day and we still went out on "friendship dates" and hung out, but they had more space and more freedom to identify as partners without people asking "But you have a wife!?"

They are living together now, they are on the same page about love, sex, marriage, kids, and many moral issues. they make a great team.

The transition from high school sweet hearts, to spouses to just friends was so smooth, we never felt upset or depressed over it, Polyamory allowed us to be happy throughout our entire relationship.
