Eww, German? Sorry, I don't find anything sexy about that language, it's too harsh with way too many hard consonants, and the high amount of "ch" (as in "Reichstag") sounds are like nails on a chalkboard.
I like Spanish, Italian and Greek, and French is pretty sexy too. I find the romantic languages are the most pleasing to the ear, it almost sounds like they're singing the words, rather than just saying them. :love:
