Is There Something Wrong With That?

I know a boy since 2015, at the time he was 9 years old and I was 15 years old, I always thought he was handsome, when he turned 12 he realized that I liked him, but I never had the courage to try something, nowadays he is 16 years old and I am 22 years old, we are both male and my desire is to suck his penis, so I would like to ask him now that I have the courage.
