While the relationships in the Greek mythology are fluid, there is some notion of the marriage between Greek gods. My question is - is there any official same-sex marriage in the Greek mythology or some kind of relationships that are like marriage? Or maybe all same-sex relationships (e. g. https://en.wikipedia.org/wiki/LGBT_themes_in_classical_mythology) were for the pleasure of body and soul only?
I can not find such marriages in the internet and I guess that there are none simply because the ancient society has no similar notion of same-sex marriage in the human domain.
