Ok your answer is quite 'normal', I guess you think there is a big difference between 20s vs 30s, even though I think a 30s man is better equipped to be a father and husband. Also I think there should be supervision in courtship regardless of age because a man and woman who are not married should never be left alone together.

Yes I understand where you are coming from, since the Church does indeed clearly teach, that for under 18s parental consent is REQUIRED for marriage. There are certainly girls who are um 'well developed' by even 14 (to the point you would assume they were older based on their looks), but in other cases like a family member of mine, she did not reach menarche until 13.

If you don't mind, what ages do you think is ideal for marriage for both man and woman? I personally agree with Aristotle for about 18 for most women, with exceptions being case by case, but for men I do not agree with him on 37 for the man (but I do understand the big advantage 37 has for a man in terms of finance, life exp and maturity) but around 25-27 because I think most girls do not find older guys (too much older or rather old looking) attractive. There are certainly some men who look much younger than their age say early 20s while being late 20s and this may give him more appeal with the younger ladies but most men do not age like this (especially if they do not take care of themselves). I am not a parent so I don't have personal bias e.g "Daddy's princess" for not letting my daughter marry, but some parents are like this, they can't accept they have a young woman and not a little girl even if she will always be their little girl, and this can lead to disastrous consequences if they rebel due to not being treated seriously.

So you disagree with Aristotle.
