can it be the same work if guys are more, "ambitious and proactive"?
Refusing to let you **** them has nothing to do with whether the woman is proactive and ambitious at work. Your analogy is ridiculous.
First, if guys are ambitious and proactive about full body massage with a happy ending, it is because they want to get *****. A woman already has that.
Second, if such short term goals and hedonistic attitude is what you call "ambitious and proactive", I hope you never try to run a business.
Now, why should women work doing the same job and make less?
