I think so yeah.
I knew I was homosexual since as far back as I can remember, sure I didn't feel it as much or explore it, but it was there. As a kid I just used to deny it to myself and ignore it, if it came into my head.
The good thing about talking about that sorta stuff to other 6 year olds is that they don't take the hint. I told one of my 6 year old mates that he was pretty in like, reception. He didn't think anything of it. Funny thing is, we're now going out!
