notpicker you started two threads!
I’ll repeat myself here
The truth of the matter is that it’s not based on age. It depends on when you mature. For some people it’s 18-19 (most boys not) 21,22,23,24 etc. Even if you’re expected to, it won’t change anything. It all depends on how mature you are. I know several people who got married young. One got divorced a year later. Another one I know who got married young is still married bli ayin hara. How do you expect to get guys to mature faster? They can’t go to EY any earlier. (That’s a whole discussion in itself.) Everyone has their own maturity level. I don’t think it really depends on age.
