Idk wtf to do

So I'm 16, and a virgin. I've never been fingered or done anything with a guy other than kiss. I don't admit this to people, I just let them think what they want. I obviously get turned on but I don't really know what im supposed to do, in order to masturbate. I've tried but never 'done it right' Im just so worried. Is there something wrong with me?!?!
