Well it depends what is meant with older. There are many women who are in their mid 30s or even early 40s and are still very good looking, way better than the average 25 year old. However, what can be found very very seldomly (almost never) is a 20 or 25 year model looking man with a 50 or 60 year old ugly woman - whereas the other way round we have countless examples of this (Ecclestone, Lothar Matthäus, Dieter Bohlen just to name a few). Also, young man does not necessarily equal beautiful man. There are many young men who are already bald, have a belly etc. especially in this day and age of lazy millenials. Surely a hot 40 year old woman would be a catch for them. I do not doubt however that there are even some hot looking young men going for older women, that is also due to the fact that young women who are good looking are often very selfish and entitled, whereas more mature ones are way easier in a relationship. I personally only date younger women but this is also a matter of taste.
