How young is too young to get engaged?

Asia
So this is something my boyfriend and I have been talking about recently, with him saying that he wants to know what I think about getting married young…and he knows that if he asked me today I would say yes and be planning a wedding six months down the road lol; but he always ask me if I think we are too young, and age was just something I never thought about wit this…So I just want you alls opinion on this.
