It's weird for me to think of Mickey with other guys. Especially before Ian.
Ian wasn't his first obviously and we know he'd been with women but for some reason thinking of Mickey letting another guy fuck him bothers me. Had he ever kissed another guy? He was so far in the closet it's hard to believe, especially since he made Ian wait for so long. Was Ian his first kiss with a guy?
He was with Byron, which is the first time we see him kiss anyone other than Ian (albeit from the back and looking very fake), but he was the top in that relationship. He fucked other prisoners in jail and, again, was the top. In the 'prison interview' he joked about how hard it was to find a quality top in jail. But we never actually get the sense he was bottoming for anyone else.
I wrote a story where he'd had sex with a male hooker in a nameless faceless way, as an explanation, and I actually choose to believe that head-canon because the idea of Mickey having bottomed for anyone but Ian just bothers me so damn much. And then I go down this rabbit-hole of wondering if I'm femininizing Mickey because he's the bottom? Am I being that asshole who looks down at women for having had other sexual partners and judging them but not the men who do the same? I don't think so. I certainly hate that shit when men do it. But then... it doesn't bother me that Ian fucked other guys, but it did bother me if he bottomed for them. I don't know what that is. I feel like it's somehow more intimate an act so it bothers me more.
But yeah...I don't like thinking of Mickey with other guys.
