Speaking as a CEO, who has a handbook that comports with the laws of many states, this is correct.
In all the states we do business in, which is most, it is illegal to have sex with a person who is passed out; technically, the term in the HR handbook is incapacitated.
And this is why when someone passes out at an office party or any company event, it is company policy actually to “kick” them out of the party, politely, and get them in a cab or have one of the cars take them home.
Speaking again as CEO, and knowing my company handbook inside out, this also is correct.
But, to be accurate, the number of drinks is irrelevant, it could be five or ten etc. drinks.
In no state, that I know of, is it illegal for a man and a woman to drink and then have sex, even if the woman is intoxicated. This is not classified as rape. Intoxication is not incapacitation, and the law recognizes that difference. This I know has happened at many office events (the cleaning staff speak too freely sometimes), yet not one charge of rape ever.
Plus, there are so many degrees of intoxication that it is usually impossible to judge where someone is on the scale after drinking; that is why incapacitation is the operative standard. The law acknowledges this distinction and thus the standard is it is rape if either party KNOWINGLY engages in sex with a partner so intoxicated that the partner cannot consent - and that goes for the female as well actually. I know companies where females have been charged with raping male co-workers.
Additionally, as per the law, there is no such thing as passive rape. By passive rape I mean the male and female are both drinking and intoxicated and they both are into it. However, the female is only into it because she is intoxicated and is taking a decision she would not normally take. Yet, she is engaging with the male, says yes (an intoxicated yes, but says yes in any event), they have sex, and then she later realizes she had sex, even though she did not mean to. Under the law, the male has not committed rape because there was no way of him knowing that the female was not doing it of her own free will or was not saying yes of her own free will.
To further illustrate the law, the situation could be the male is a teetotaler and his date is drinking. The female could get intoxicated and if she says yes to him and they have sex, then it is not considered rape if the male does not know she is intoxicated beyond consent. She was not incapacitated, he did not use force of any kind, and she willingly said yes, thus, no rape. Regrettable sex, yes. Rape, no.
