I've asked how to say "You are very sexy" and my Spanish friend told me "Tu eres muy simpatico." But I've read that simpatico means basically just "nice". I also see "es" instead of "eres" in some responses. I'm assuming it has to do with formality/slang of the verb and the conjugation. The jist is--my best friend who is always saying things in Spanish to me (to try to rile me up) and having me try to guess what he's saying. Now it's MY turn!! :-) I want to say "You are very sexy" to him and I was just wondering what was proper with this. Thanks!
