Is being a gay 'daddy' limited to age?

The phrase that gets tossed around in the gay community is 'daddy.' But do you really have to be 35+ to be described as 'daddy' in the gay community? Im 23 and have that 'dad bod' and all I want is a younger bf (18/19) that I can spoil and go on cute dates with, etc... Does that make me a daddy? I also find that the majority of gay guys in Toronto aren't into the 'dad bod' look.
