How did you realise you were gay? what did you do ? how did people react?

One day I was watching the movie Troy, and when Brad Pitt appeared almost naked I realized I was gay, it's not a joke, it's the most remote even I recall in which I could realize that I am different. Time ped and I just didn't give importance to my uality, I had better things to be thinking at, thou I never denied it to myself, although I had a phase in which I as because the ambient around me was phobic and so I wanted to hide my ity with phobia, then I tried to hide it with saying I'm aual. Then I saw a movie called Velvet Goldmine and became proud of myself, and so I started coming out to people, each time it was easier, nowadays it's like if someone asks me: "Are you a ******?" I reply "Any problem with that?" Really, that happened. My close friends reactioned very good, some of them suspected, other people who weren't my friends acted like if they accepted me but in my back they discriminated me, and I didn't care, just as it's OK to be gay it's ok to be . My mother had a little shoch when I told her, my sister thought it was a joke, my brother was happened to be haha, my other sister is OK with it, my father said he'll never accept a gay son, one year now has been since I told them and my mother has changed her views, and my father I don't know, but the day I told them they were just too concentrated on having a bad reaction, on telling me they'd never accept it, on telling me I'm in a phase, and such...
