hen i say older i mean around 10 years older or so, maybe a little less but always atleast 5 years older. This is weird
I don't see anything weird about it. In general Women develop faster than men, in most aspects - mentally, socially intellectually. Men eventually catch up but the wait is too long so women do what they feel they should do.
So for a woman to find a peer - someone on the same intellectual, psychological level - more often than not, she will need to look for a man older than herself. Otherwise she ends up with a boy.
