Toy Story Boys Necktie At What Age Does A Child Establish Their Sexual Orientation?

At what age does a child establish their sexual orientation? - toy story boys necktie

I fear that my 3-year-old children (45 months) loves it, everything is pink, the princess loves the stories and toys, etc. He loves boy toys, but the obsession with pink during the last years. We fear that might be gay, it's not a terrible thing, but hard enough in life without the image. Any advice appreciated.
