I think it depends on the age of the other person.
If a lady is mid 30's then obviously the guy needs to be mid early 20's.
50 and above I guess 45 and under.
I think a toy boy can be any age where there is a significant age difference between the man and woman.
A cub, however I would think should be 18- mid twenties.
"How old is too old to be a toyboy? I swear overnight I've gone from toy boy to outside middle age couples age range looking for younger guys "
Haha same here
