Hm...if he holds your hand could be attraction or that he likes you
If he puts his arm around you or around your chair..sexual attraction
If he touches your face...attraction and possibly emotion
If he touches your lower back...sexual attraction'
If he touches your shoulders firmly, especially if he also touches or is close to your neck, it's probably also attraction.
If he touches your ass or t*ts...sexual harassment :P
