VMB Readers: What is The Appropriate Age For a Girl to Get Married

A VMB reader sent this:

Hi VONIgroup,

Please i need your readers opinion on this. Please what is the appropriate age for a girl to get marry? I've meet some people on this issue, though some told me 25, and many more matured people says 23, some even say 20.
Am indeed confuse on this, but i remember that my dad use to tell me those days that the minimum age for a girl to get marry is when she feels she's comfortable enough to stand as a helper to her partner.

But what if you are not Ok but old enough but? I am a lady of 25year, am getting old everyday and my partner is ready. What do i do? Please i need people's opinion like i said.
