the forearm is probably the most unpainful place Tom, 2 of my good friends both got tattoos there, one when he was 15, one when he was 17 (parents aren't strict). lol, why are you asking if it hurts? if someone says yes or no, it's not gonna change how it feels.
as far as my opinion on tattoos. I don't think you should get a cross unless you are heavy into god and shit, I think that getting tattoos that are meaningless and easy to see is stupid, unless your famous. I say that because if youre famous and shit, you don't have to impress anyone, but if your a common person, and youre trying to get a serious job and someone sees a dumbass tattoo, your chances lessen.
my mom said I could get a tattoo when I was 15, and I was about to get a god damn HEARTAGRAM TRIBAL like bam, but good thing I realized how serious tattos are haha, and Im so glad I decided to wait until I absolutely know what I want. (my friend got the bam tat, and regrets the fuck out of it.)
the only tattoo that I think is reasonable for me is getting my last name. one, because that's never gonna change, and two, because my god damn las name kicks ass.

BUT
I think I am gonna wait because you don't know how much you are gonna grow, and Im pretty sure if I get alot bigger, the tattoo will look fucking ugly because it will be all stretched out and distorted.
"The End."
