It depends on how he touches you if he pokes you he's bugging you as a friend but if he rubs you on ur side he likes you
it mean's they like/love you and they wanna have sex with you
you probably like him
It means different things, depending on the relationship. You did not mention what the boy is to you.
it means he likes you.
He prefers you to sneeze on it
it means it could be the start of something good
that is a wierd way of saying hes trying to cheat
it depends how he touches it. if he wraped his arm around you and held your side he is probably interested in you. or maybe it was just an accident,but I think the first thought is correct
electrons
He is obcessed with you he wants to date you and he wants your germs so much play cool
It means that he isn't ready for a committed relationship.
A guy may rub a girl's waist if he likes her. A guy may also do it accidentally when walking by and it may not mean anything.
