I don't disagree what you are trying to say.  I just hope for a little more clarification.

What do you mean when you say women are designed to be self-focused?  Women are designed to raise children, how is that self-focused?

Self includes their children/family.

Abraham was 10 years older than Sarah (Genesis 17:17), and after the death of Sarah at the age of 127, Abraham married Keturah and fathered six children with her (Genesis 21:5,23:1-2,25:1-2)
Isaac was 40 when he married Rebekah, and 60 when Rebekah bore Esau and Jacob (Genesis 25:19-26)
Esau was 40 when he married two Hittite women (Genesis 26:34-35) - although it should be noted that Esau is not held up as a Biblical role model
Jacob was about 80 when he married Leah (various passages)
Moses was over 40 when he fathered two sons (Acts 7:22-29)
David was 30 when he began his reign as king of Israel, afterwards taking many wives (2 Samuel 5:4)
Zechariah and Elizabeth were "getting on in years" when John the Baptist was born (Luke 1:5-7)

And from some other, extra-Biblical sources, a similar story:

According to Jєωιѕн midrash, Ruth was 40 and Boaz was 80 when they married
According to apocryphal sources, Joseph was 40 when he took his first wife, who died when he was about 89 - after which point, he took as his second wife the Virgin Mary

Honorable mention: even in modern times, a couple of Popes were born to fathers of advanced age:

Pope St. Pius X was born in 1835 to Giovanni Battista Sarto, ~43, and Margherita Sanson, ~22 (source)
Pope Benedict XVI was born in 1927 to Joseph Ratzinger, Sr.,50, and his wife Maria, 43

Another source

Giovanni Battista was 41 years old when he married, the 13th February 1833, Margherita Sanson (1813-1894): the bride was only 20, and their marriage was consecrated by the chaplain Father Pier Paolo Pellizzari (S.Vito d’Asolo, 1807-Vallà, 1875).

20 is still a few years younger than 22. If woman want a large family, and fathers want someone reliable for their daughters, older men are the best option. That's simply how it was always done when society didn't have "safety nets" (many of which are bad like encouraging fornication and fathering of bastards) as the man needed to be a stable member of society.

  More feminism/male-hating in action. 

Not the author of "Then why don't you get off the internet and get your home/finances ready for your future bride and family?", but running low on patience with hyperfixation does not (=/=) equal "feminism/male-hating".

Just food for thought: often, a particular criticism is not comprehensively valid or fair but it is relatively rare that it has absolutely zero merit.

I guess OP is just bored/struggling with temptation while he "prepares" himself. Between work, eating and sleep there isn't too much for someone to do until they have their own house.
