"…men can’t get an erection without wanting sex, according to physiology."
There’s a difference between becoming aroused and wanting sex you fucking nitwit. A number of women experience arousal and orgasm from being raped. Does this mean it wasn’t rape? No, they still didn’t want it and in fact that ends up making the recovery worse because pieces of garbage like the poster in the image above make them think orgasm/arousal means they wanted it.
The human body is a biological machine. As such there are certain mechanisms within the body that are outside of human control. Especially under certain circumstances. Nipples become perky from stimulation or when it’s cold. You process food into fecal matter. Your heart beats without your conscious input.
In that same way, with stimulation, a person can become aroused and even orgasm without wanting sex.
tl;dr - the poster in the image cap is wrong. So very very wrong. And if they said this to me in person I’d probably just start screaming profanity at them.
