As I walked down the stairs in a bar a younger man passed me, walking up the stairs. As he passed me, he put his hand straight up my skirt and touch my vagina quite forcefully. My skirt wasnt excessively short, only slightly above the knee. Even if it had been shorter, I have a right to wear what I want without fearing someone will touch me. I did not know this individual, I had not had any interaction with this person. It was an opportunistic assault. The venue was packed. I could not turn around or chase after him, due to the huge volume of people herding us along. He vanished into the crowds. I was frozen in shock. At that moment in time, I felt like I had to just accept that’s what happens on a night out in a ridiculously busy venue. It happened 10 years ago and I still to this day feel angry, humiliated and violated.
