i guess that depends on if you are the parent of the girl or you are the girl.
Ask her:)
Nothing wrong with that
Find him a hot 19 year old girl
Yes, why not?
no
Helll Yeahhh !!
YES!
if you are the 15 year old boy tell her how you feel about her. if you are the girl then tell him how you feel about him and tell him it cant work.
yes it is the 15 year old is still under age.
legally no that is basically robbing the cradle, if you know what that means, and why would you want to marry a 18 year old girl if your a 15 year old boy anyway?
No. It is perfectly ok.
