Is it bad for my younger brother to be very naive?

Anonymous
He's 19 years old (will turn 20 on May 5) and is very naive for his age. A couple days ago we had a family reunion and even an older woman asked him if that was his first time he ever drank. He said yes and looked away, not knowing what else to say.

He has no malice in his mind and hasn't been corrupted. He wants a girlfriend (he never gone out on a date ever) and romance. He reminds me of my male counterpart. I was once a very innocent girl and unfortunately landed a user. I don't want the same thing happening to him with a terrible girl and then him turning into a jerk that pumps and dumps girls because of that.

Is it bad that he's very naive for his age?
