My story is very similar to yours mate. Was brought up in Sussex, nowhere near a league football team, no local loyalties therefore and family weren't into football at all, so I was strange and on my own from the start (the words of Blue Moon have always held a special appeal to me for this reason). Neighbours were from Manchester though and supported City so thats how it started for me in 1981. First match I saw us live was in FA Cup 1983 at the Goldstone Ground, we lost 4-0 so certainly wasn't a glory hunter then and I still aint now!. First time to Maine Road I went in an official Brighton supporters coach, got out at Maine Road and whilst they all trooped off to away end I went and stood in the Kippax on my own as a 15 yr old - in hindsight was probably nuts to do that but the atmosphere of fear and excitement was unreal and my memories of it are as vivid today as they were then (I remember when we scored ending up about way down the terrace even with the barriers)
I spent many years living around the world and whenever people knew I was English they'd ask which team I supported, when I told them City I almost always got looks of 'who?' and what there's 'another team in Manchester?'. You just get used to it.
I'm as loyal as any Blue, circumstances mean I can't go to as many games as most of you but I feel the pain of defeat and the exhilaration of victory as much as anyone. I accept my place that because I can't go to as many games as I'd like that it means I can't also go to finals and big games, whereas those that do go every week get priority.
But I hate others thinking I'm any less a Blue just cos I don't have a Manc accent.
