But it seems to me the correct reaction is kicking the cunt in the balls, and marching straight out of there. It's not sitting patiently while he gropes you, telling him that's not very nice. It's certainly not going back to chat with him again.
Uhm, I really like your courage. But they say if you're in that situation, most likely you don't know what to do. The shock and fear are already overwhelming, and that makes them not able to move or do something about it. Most sexual crime victims often hate themselves for that and that's just sad to hear.
