"Em không "làm" người lớn đâu anh" - How can I say it in English?

"Em không "làm" người lớn đâu anh" - How can I say it in English?

With my present knowledge of English, I'm not able to translate "Em không "làm" người lớn đâu anh" into English.
Please!

"I don't wanna grow up" will do. i think.

You can try to resist
Try to hide from my kiss
But you know, but you know
That you, can't fight the moonlight

There are several ways to say it :
1 -Honey, I don't want to go to bed with you just yet .
2- Honey, I want to keep it until the day we married.
3- What ? You want to go to bed with me? You 've got to be kidding ?
4- Hahaha, What did you just say again? You love me ?
5- I don't want to be like the grown-up yet. Let's just keep it this way .
Ok, it's still depending on the situation...

oh, i thought it's like, in a song, the girl doesn't want to fall in love with a guy and "don't wanna grow up" is her reason to refuse his love.
Đừng yêu em anh nhé,
đừng yêu nhé
em không làm người lớn đâu anh
Đừng yêu em anh nhé
đừng yêu nhé
em muốn làm cô bé vô tư ...
I could be wrong then....

Cause my body too bootylicious for ya babe

Oh, no, if a girl speak "Em không làm người lớn đâu anh" to a boy, she doesn't quite refuse the love. Therefore I don't think it isn't easy to speak in English.
