We have this saying here in Holland : you have to learn it on an old bike ( which refers to a man having his first sexual encounter with an older woman )
And after some personal experience I completely agree with this saying !
The reason I like to go out with older women ( 1 - 6 years older than me ) instead of women my age is due to the fact that they seem to be less childish, less superficial and more fun to be with all around.
