I'm in my late thirties now but I came out to my mum in my late teens and told her I was bisexual. Her response was to call me a fucking slag and that I wasn't because I was sleeping with lots of men (I was sleeping with lots of men as a defence to try and not be attracted to females because I knew it wouldn't go down well). Anyway, twenty years down the line and i'm still attracted to females as well as men which is no surprise.
My experience of coming out was horrible and has shaped part of my life. I've always had a presence in the gay community though but I identify as straight for an easier life.
