I think that a suitable present would be something like jewellrey. Something to keep for ever and to pass onto next generations.
is it a boy or a girl
jewelry like a diamond necklace diamond anything
a car not a exspensive one but something around 3000 dollars
Money!
It depends on what the girl likes cause many girls are different so you have to know what they like to get them a perfect birthday present
a lambo!!!
A good 19th birthday present for your 2-year boyfriend would be a fancy smartphone.
bottle of booze. or maybe a new pair of sunglasses or a really nice purse like MK or wtv is in
A paintball gun
A small dildo
Well depends how much money you have and if she's girly or not!
i would give the a ipod
