There can be lots of reasons for that. Certainly it means that he doesn't have a problem with you getting that close to him, which means he has a certain trust towards you and he likes you. If he doesn't only let you touch him but he enjoys it when you do, then he most likely has feelings for you.
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
It means he has yet to learn some good manners and is in danger of receiving some form of punishment sooner or later
you probably like him
ass grabbing xD? sexual harrassment..:P
It means different things, depending on the relationship. You did not mention what the boy is to you.
it means he likes you.
No. Body fluids have to be exchanged to be called sex.

He prefers you to sneeze on it
it means it could be the start of something good
