I did chick who can walk on the ceiling. But seriously, you are definitely fuckable. Way more than a 3. Sounds like your old man needs a reality check. The two of you walk into a bar. In a loud voice ask "how many men here would fuck me right now if I asked?". Then have him ask the women how many would do him. Guaranteed you'll do better. Afterwards just look at him and say "well, if I'm a three I guess that makes you like what? negative 5?"
