At what age did you know that your child is gay?

Please dont jump down my throat and tell me that my child is too young to have a "sexuality". He is 7 and I remember very clearly at age 8 how I was soooooo in love with a boy named Isaiah. My son is very feminine. Loves to play in my heels and dresses. Loves barbie dolls and playing house. Wore a purse into the grocery store yesterday and when he make believes he's always a princess; instead of a prince. He will compliment both genders appearance. If it's an attractive guy he will mention how handsome they are and with a female, how beautiful. He tends to watch more "girly" shows. Has a knack for decorating and designing. Might I add that, I am his only role model. His dad has been physically present in his life (lived in the same house, married for 9+ years) but his dad has never really tried having a conversation with him or spending ANY time with him. His dad has been a financial supporter but, nothing more. Maybe my child acts this way because he only has a very feminine woman to look up to and is around 24/7; literally (he is even homeschooled). The homeschooling may also be a factor in the way he acts because, he is more able to freely be himself. I must state that no matter his sexuality, I'll always love him the same. Also, I always encourage him to do whatever makes him happy and allow him to creatively Express himself. Just wanted to know. Please NO NASTY COMMENTS. via /r/Parenting http://bit.ly/2vAhDwv
