> As another gay man, I used to be radically skeptical of monogamy. Like in my 20s I was spouting the line that it's a heterosexual construct falsely imposed on us for moralistic reasons. But both personal experience, and a widened social group, has led me to believe that, for a significant number of gay men a monogamous relationship is ideal. They're happiest in them, and seem to be able to make them work. Perhaps with some compromises and perhaps not entirely happy, but for what it's worth, I'm not sure I've met any couple that was perfectly happy.

Funnily enough I am precisely the opposite. I spent my 20s trying to hunt for "the one" and had a series of short, failed relationships. Now I'm in my 30s I am in a 9 year long successful (I think?) open/polyamorous relationship.

Really I think gay men (and men in general) struggle with communication skills and emotional maturity. Gaining those skills are key to maintaining long, healthy relationships. Non-monogamy is an avenue towards working towards achieving those skills because maintaining a healthy, open relationship means a lot of communication is required. In my opinion, it is a high risk, high reward strategy to a maintaining a relationship.

I think we have to distinguish minor annoyances from major communication issues due to sex. Like it or not, sex is a big part of being human and sex drive is something can be wildly different between people. Non-monogamy can be an outlet for this.
