If a man only seeks out a young lady for her age, then there's going to be problems
Everyone gets old, so if young woman reaches 30 will you bin her for a 20 year old? What if no 20 year olds females like you and find you unattractive when you are in your 40s to 50s? could be toothless then and balding.
It's good to be in same generation be able to share things like TV etc we watched when we were younger.. couldn't do that with someone younger, wouldn't they not make u feel ancient?
