If your primary-school-going son asks you what the meaning on being gay is, how would you explain it to him?

by being honest about it. tell your son that there are different types of love relationships, and not just a girlfriend boyfriend types, even though it may be more common. a gay is when a boy and a boy are in love and like spending time with each other. be very casual and normal about it when you speak, so that your son understands that it is another way of expressing love and not something differnet.
