Actually, many of the Desert Fathers highly praised the Desert Mothers who did not pose as young men (not eunuchs) in order to join all male monasteries, but formed their own communities of women/virgins or lived on their own as solitaries in the deserts of Egypt, Syria, and Palestine.
There were, of course, women who posed as young men in order to enter all male monasteries because of those monasteries’ reputation for living a much more severe ascetical life. The women wanted to prove that they could endure just as much as the men could. And I’d say they proved it quite well!
As to the rest of your posts, I’m not quite sure what your objections are. The Church has always been very clear that sexual relations between a husband and wife are not only a good thing, but a very good thing when entered into in accordance with God’s plan for marriage from the beginning.
When it comes to looking for advice, I think most of the folks who post here would be honest enough to say that they seek the advice of anyone (regardless of age, race, gender, or time-in-which-they-lived) who has extensive experience in the spiritual life and has demonstrated the highest levels of holiness when held up to the standard of the Gospels. There are certain things that are constant throughout the centuries. One of those things are what constitutes vice, what constitutes virtue, and the struggle to uproot vice so as to live in virtue.
Incidentally, the Bronze Age ended several hundred years before the coming of Christ. The Desert Fathers and Mothers lived several hundred years after the coming of Christ. But frankly I don’t really care when they lived. They give good advice when it comes to self-control (whether in the area of sexuality or in other areas).
