First, a woman should say STOP!
Which isn't something any of Arnold's accusers did from their description of things. A lot of guys get over zealous if they think a woman's flirting with them. If they're mistaking a situation, the woman should let the offending guy know first before telling someone else. If he still persists, then it's ok to slap him and complain to others.
No means no, but you have to say it first.
