I would be perfectly fine with it, and would allow them to safely explore their curiousity. I have 2 children (4 and 6) and have been in a committed homosexual relationship for the past 2 years. I do not see anything wrong with being like that, because in my opinion you can not help who you fall in love with. I personally don't look at a person's sex when determining if I like them or not, I look more at who they are as a person, and how they make me feel about myself. You can't discouragethem or scold them on the issue because of your own beliefs, this will most likely cause the child to rebell and go against waht you prefer for them just to spite you.
