Well, it's kind of an odd question. It must mean something like, "What do you like about being a boy, as opposed to being a girl?" since the question could otherwise be phrased as, "What do you like about your life?"
What reasonable answers could the young males have offered? "I like not getting a period." "I like the fact that no matter how much I have sex, I'll never get pregnant in my entire life." "I like being able to pee standing up."
OMG! That IS my favorite thing I enjoy as a male! I can write my name in the snow!!!!
