I recently found out my younger daughter ( she'll be 25 soon ) was bi and that only came out when she asked me how as her dad I would feel about her decision, she also told me that her mum was not pleased at all.
She was pleasantly surprised when I told her outright that its her choice respective of her preference and that it is not for me or her mum or anybody else to say what she does, if that's her choice then that's fine, needless to say she gave me 1 hell of a bear hug and couldn't stop thanking me for respecting her choice.
I had a similar conversation with my dad once after he told me my step brother was gay, my dad was very disapproving and consequently they never spoke again but my dad got the shock of his life when I turned round and told him that it was not up to him to say what my step brother should sexuality wise, it was his choice to make and he made it.
To the_itgirl do not feel like you have to try to be what you don't want to be, if people cannot accept you for what choice you make that's their problem not yours, don't ever let anybody judge you, you are who you are and that's not for anybody to question.
