My boyfriend wants to get me a gift...?

My birthday is coming up. I don't know what I want for it and I'm tired or telling everyone I don't know what I want or I don't want anything. I'm turning 15, any suggestions on what a 15 year old girl would enjoy? :L I don't like girly things, like jewelry, pink stuff etc. I like hard core, metal core, death core, metal core kind of music haha.
