When I was in my late teens/early 20's --- this would be 40 years ago --- I was in a number of work situations with minority males. If I were alone with one of them in a room or an elevator or a car, almost every one of those men would try to grab, clutch and kiss me or worse. It was made clear that if I complained, I would be in trouble; they wouldn't be.
They never tried it in groups, and never tried it where there were observers. The only way I knew to deal with it, was to avoid them at all costs. It was, I think, before the term "sexual harassment" had been invented. I thought it was "just me." I was too dumb and naive to realize they were doing it to all the female employees.
As for physical resistance, I always struggled free and they never pursued. But I was aware that any one of them --- even the old guys-- could have broken my jaw with one blow. That does tend to dampen a girl's fighting spirit.
I do think everyone should learn to fight. If I had daughters, they would have ALL gotten self defense training.
