Women do not come forward because no one believes them. 
I learned that when I was 15.

My first sexual harassment happened from a star hockey player at Service. I told the administration and the security guards - who were his coaches. Did ANY of them believe me? NO.
They spent far more energy blaming me for having my locker in D hall, for being in the same hallway as him, and for 'provoking' him (I always wore shirts 3 times too big to hide myself from attention - wtf?) 

So THAT is why women do not come forward about unwanted harassment, unwanted touching, and rape. Because we are taught by people like those on this forum, that what happens to us does not matter - it is our fault. 😑

And here are some AK stats to back that up:
