dose age gap really matter and why
It depends.. If its a 30 year old man and a 15 year old girl or the other way then ya that is a bit of a issue. Just depends on the ages.
what age gap?
To me it matters at a certain point...
Depends on the age gap. If it's an adult with a minor, then yes it matters very much but if it's two adults then not really.
yes and depends.
