Public Masturbation On Bus: “He winked and smiled at me”

I was on the bus going home after work one evening in New York City. The bus I was on had mostly men in it. After about 10 minutes or so on the bus I realized that the guy standing next to me had his hand in his pants and was masturbating. I couldn’t move away because the bus had too many people in it. After I got off he got off too and started following me for a few blocks he was like “smile baby girl” I just ignored him and when I turned around he winked at me, smiled at me, and said “wait up”. But I said “F*** you!” Then I left.
