Son is gay

My 10 year old son began crying on his way home from school today. Of course i asked him what is wrong and he proceeded to tell me he thinks he is gay. I told him his feelings were normal and it is okay for him to like whoever he likes. He kept crying and said he doesn’t want to be different. He has had many crushes on girls so i asked him why he felt he was gay

And he told me he liked a boy . He said he didn’t know the boys name or age. I’m proud of him for telling me but deep down I wonder if he having lots of feelings and a bit confused. The reason I say that is he was just telling me last week about a girl he liked. Now of course i don’t want him to keep this to himself but I don’t know if this is something he should be openly talking about until he gets to a dating age. Thoughts? Advice on how to support him ? I just don’t know if having him tell everyone is a good choice either.

Update: thank you everyone for the support. My son has been crying and seems to have a need to tell everyone. He has now told me his stepdad and his father. He wanted to tell his brother 14 and I told him not to. He asked about telling his friends and began to cry saying they wouldn’t like him anymore. I have to find a way to have him be 10 and worry about discussing his sexuality later in life. Any ideas on this? I don’t want to make him ashamed to tell people but I also don’t think this is the time to announce either .
