Does this make me a tease?

If a girl puts her head in my lap yeah I take that as something more than flirting. (People are different though--in rare cases a guy might not think anything about it.) Any kind of physical touch can be taken as meaning you want more. If you read books, it will tell you touching a person's arm or leg or something is a sign they have more than a "social" affection for you. It may not be love but they feel something more than they do for most people.
