The best thing about older women, for a younger man, as a rule is not that they know how to have sex better but they are more willing to do so. Some women will have issues, but I met Mrs. Chicup when she was just 18 and that young fragile respectable girl road pretty well
For a young man, and I was one myself once, if they have a choice between a 20 year old and a 40 year old, they are taking the 20 year old. Its when the choice is between rosy or nothing, or a sure thing or a big maybe, that the 40 year old wins out. (I am of course assuming looks are relatively the same minus the age difference).
