Wanted to know if it is permissible for me a 19year old male to marry a non-muslim woman. And if my parents want me to marry a Muslim girl, whats the ruling on that. Is is permissible to have sex when ever i want with her permission via Mutah.

It is permissible to marry from Ahlul Kitaab. Your parents may not prevent youas a man but they can only convince you.
