Naw, Lulu. Deut's husband is young enough, and his second wife is old enough. They're all 3 good folks. Friends of mine, whom I HIGHLY respect. Those weren't the reponses he was getting from his second wife, but from fellow "Christians" who were seriously missing the pouint of PM. Happens all the time.
You're NOT obligated to go marry whomever announces that he wants to marry you. You are NOT an inanimate object, and the little boy "I saw it FIRST so its MINE!" does NOT apply.
Neither are you restricted from marrying an older man if that were where your heart led in collaboration with God.
This is an area where God has NOT legislated appropriate choices (though if your choice was 12 there would be other problems ...), so your free will is free to choose. Don't let anyone make you feel bad for choosing.
It is perfectly logical for a woman in her 20s to want to marry someone of similar age, and to explore the adventures of life and learn their lessons together. There is logic in other choices as well, for other people.
So go for it. Select someone who pretty well matches up with what you seek. Ask God for guidance, by all means. But the Word says that He'll grant you the desires of YOUR heart, not the desires of whoever happens to first say, "Hubba, hubba! I want me some o' DAT!"
Sheez, Louise! *chuckle* Let's give God credit for being nicer than THAT! *grin*
