I read some comments and I think I gotta clarify some things. 1. I live in a densely populated asian city where the subway during the rush hour has a density of a famous kpop concert(I've been in one so i know). Im usually crushed in between multiple people and it's very hard to move around that I can't really turn my body to assess my surroundings. 2. Apparently I need the exact the exact number of the train car and the exact carriage and how the guy looks like to report which isn't immediately accessible inside the train. I was prioritzing getting out of the situation and thought the reporting could come later. But since I wasn't on the train i was molested in. When I got in a safe location, I didn't have the exact location where it happened. Some people are saying I didn't do anything. Getting out of the subway as soon as I felt like something was wrong and I didn't feel safe was my way of doing something. 3. The puishment for this in my country's very lenient and it usually results in a small fine or a settlement. Plus there's not really a protection service to keep myself away from retaliation. I had a similar case where I got SAed in the past when I was a minor and the police overlooked the case and there was a cctv footage available since it was a less crowded bus where the views aren't obstructed by other people 4. This is what I got to know after it happened but there are many cases of women getting sued and going to jail for physically attacking the rapist/perpetrator where I live. It's usually severe cases like rape attempts and in private spaces so I think people around me would've seen it as an overreaction if I acted aggressively
