I had something similar happen to me on a train. The guy didn't touch me, but sat across from me with his legs open and hands between his legs. Next thing I know his hands are moving much more than they should be. I felt disgusting. I reported and was told there is nothing that can be done about it because he wasnt doing anything illegal (bulls***!!!!!!!).
Having said that though, its a good idea to still report it. The more women that do the more the police may start to take some notice.
Chocolate is an ideal cure

please tell the police and don't feel embarrassed about it, that guy is a dirty little pervert and needs to know he can't get away with that.

someone i'm very close to was attacked a little while back and it's people like the guy on the bus that will go on to do horrible things like that.
