It is not about having children..It is just that fertile women generally also means s--ually appealing and younger women...one may use protection and then enjoy the charms of the woman, that ensures no children no responsibilties
The last age when a woman is s--ually appealing is around mid to late fifties...3-4 years since their menopause...and that too being generous...........last age a man is s..ually appealing is mid to late sixties..and that too stretching it
There is no point in enjoying a carnal congress with a 60+ woman even when you are a 60+ man......57 is the last honourable age for a woman to have carnal congress....67 is the last honourable age for a man
