Since women naturally age faster than men, its not advisable for a guy to marry a girl his age or within his age range.
Guys need to marry girls they are far older than with at least 10 years, so that when she’s aging everything will still be balanced. You can still be enjoying her breast, and also admiring her full waist line for a long time to come.
Compare to when you marry a girl that’s only 3 or 5 years younger than you. Before you know it, she’ll start looking older than you apart from adding weight anyhow after giving kids.
So, let there a space of like 10 years between you and the girl you want to marry, just like fathers used to do it in the past.
