こにちは！
 

はじめまして、　私の名前は　クリストファーさん　で す。
I　was looking for some help for my tattoo that I would like to get.
I would like it to say, What's my age again? In 日本語 but this is as far as I can get! Help would be appreciated!
私の何歳ですか。

A couple of things to point out here. First of all, it's こんにちは.

Second, you don't need the 私の名前 part, just say 「私はクリストファさんです。」 Also, you don't use spaces when typing in Japanese.

Third, think before you get that tattoo... first of all, it's a pretty odd thing to get tattooed on you. And do you really want that? Is it something that in 30 years you could look at and still like?

And last, the only way I can think of to say that would be "私の歳は何ですか？".

In what context do you want to ask that question? Is it a humor to imply that "I don't know my age" on the tatoo or something like "Don't ask my age"???

I have to ask the same thing...

Why are you going to get a tattoo in a language you don't speak?

Yes.

At least learn better Japanese then it may be a tad bit more acceptable. But not too much more.

I don't even find it acceptable unless you were fluent in Japanese, but a tattoo would be a horrible motivation to learn Japanese, imho.

Indeed it would. I have a friend in Ireland who got a concealed tattoo. It's a Japanese sentence, I don't remember what it says. But he speaks perfect Japanese, so I think it's not so bad. And he's not like "omG hay u Guyz chekk diz cCooool awesum symbulz!"

Yeah, that's totally cool with me

First of all. If you liked Blink-182 at all. You would know why I am getting the tattoo. Blink-182 makes me feel younger. I'm 19 but I act very young sometimes. Therefore I would like to get a tattoo representing my youth. And it's the summer and I've only taken one semester of Japanese, so I have forgotten a lot. But anyway. Thanks for not helping and everyone being a complete douche bag, just because I put spaces in or elongated my introduction. So thanks for not helping me at all!
