Turn-ons would include having all arms and legs and preferably not dating other guys. I also have a thing for really short or really tall girls. Or girls that are kinda medium. Any kind of sports fanhood would be a plus, but it's never a dealbreaker.
Turn-offs would include girls who don't like leading an active lifestyle and chewing with your mouth open. Not a fan. I also don't like Canadians or people from Nebraska for whatever reason.
