Does your Hotwife like younger, older or similar in age men?

When we first got into the lifestyle, my wife had an age range in mind. We're now 42F/45M and her range used to be 30 - 45 simply because we found younger guys a little less into the idea of FWB and more into the ONS/hookup idea. Everything evolves and my wife opened up about the idea of enjoying attention from the younger college age guys. Not the cocky type that reference themselves as "Bulls" at 21 years old, but maybe the less experienced cub type. She feels like she can be in more of a dominant role in that situation as to where the similar in age or older guys she takes a more submissive role. Any other Hotwives interested in similar style of play?
