Got touched by a stranger

This happened today at Borivali station platform 2 at around 6:45pm I was near the door as the train was reaching towards the platform but during that time I felt someone's hands near my private area and it grabbed my balls I felt scarred and I shouted but nobody cared as they were eager to get down I don't know who did it but I got very angry due to this so as the train approached on to the platform I did not look behind but I too grabbed someone's private part got down and ran away before the train came to a stop I did not look behind or whose parts did I grab but I just ran away towards the exit it was really a scary experience for me this has never happened before although l've heard quite a similar things going around but I never thought it'll happen with me this is just a rant as I really don't know what to feel
