You don't seem able to understand the larger issues, the complex and complicated ones that come with sex and sexual consent. Your narrow take is that the minute her lips touch his penis, she can't say shyt, and its not true. She's also a... what, 23-22 year old girl in a celebrities house? The issues of power, control, humiliation, shame, pressure, violence, fear. Sex is not getting a girl to perform oral, or getting her to let you have sex, it is both parties wanting it. I know all this first hand, though I am not an abuser.
This was all high school for me....I saw all this shyt. Guys routinely pressured girls into sex, just like Ansari did here, and used other methods to achieve that goal.

Of course, the power dynamic is all in mens favor, in a number of ways. Not only are most women not able to overpower a man, we are not shamed for sleeping around, but praised. For many men, the fact they had sex at all is the goal, not whether it is good sex, or mutually consensual, nevermind pleasurable.
