he decided to hug me(nice gesture at first) then started to grab my rear and whispered in my ear, "I know you don't like me touching you but I realized I can go ahead and do it any way." He then kept doing it all day and grabbed my chest, too, or rubbed up against me.
That's unacceptable. And if I had been your sponsor, I would not have told you to ignore it. I would have told you to get as far away as possible from this man. I agree with Stella. His behavior is very creepy.
