Sexual assault, in my opinion, is more in the nature of males in particular having "power" or "ownership" of females and goes back for at least 5,000 years of recorded history.

Islam still denies the possibility of rape without the testimony of four male eye witnesses. 

That's pretty close to where I see your attitude as well.  

Women weren't even permitted to own their own property in much of the world, including the United States, until fairly recent times.  They were "owned" not owners.
