The truth is that explaining to children (or anyone, for that matter) what being gay means isn’t difficult. It’s about love and attraction. It’s about whose hand someone wants to hold, or whom someone wants to ask to a dance. It’s about emotion and the way people feel. It only gets complicated when adults make it complicated, when parents and other adults try to deny the parts about being gay that aren’t related to which body part gets put where, when being gay is diluted to only being about sex.
