What does a man benefit in marriage rather than responsibilies? Always working hard and thinking of how to get money for either food, school fees, this and that.... Then secondly which is the most important question, what is the best age for a man to get married? Basically to me i think it's 30.

Whatever you think your father benefits from having your mother is the answer to your question, unless you consider her useless to him.

I am sure that both your father and your mother want you to marry. Ask them why they don't prefer you having baby mamas to you having a wife.
