how do you say..i wanna practice making babies with you...in french?

Answer 1

You could try

"Voulez vouz couchez avec moi se soir" - Will you sleep with me tonight

Answer 2

That other answer was good enough.

If you wanna be nit-picky though, this would be a more litteral translation:

"Je veux pratiquer à faire des bébés avec toi".

(I wanna practice making babies with you).

Hey, that is what you asked for, and this is how you say it.

Answer 3

Je veux faire un enfant avec toi.
It's not possible to traduce exactly word by word.
