My cousin was married to his long time partner in CA when it was still legal. We celebrated this as a family. I explained to my then 10 and 5 year old that about 10% of the population is attracted to their own sex. My boy said “well, I like girls”, my girl said “well, I like boys”. I said that’s great, then everything is all settled for you. But what if one of them had said “hmmmm?” Defining it early for them is not a threat to their sexual development. It’s a path to understanding if one of them were gay.
