Oh @kyriacos you just had to step into such a controversial subject with logic and intelligence didn't you?
The only point I can even attempt to argue against is that it absolutely is un-natural
for an older male to be with a female in her early 20's
Sooner or later, words would start coming out of their mouth and the older male would recognize how totally incompatible they are. ;-)
Not really they will stick fuck and copulate with the young because they are more fertile. Nature doesn't really car about ethical semantics
