Some people use argument that “erection means consent”, so it’s not possible to rape man. No, erection is not consent. Women also have erections, in their case it’s called clitoral erection. Just like penile erection it is usually caused by sexual arousal, but that doesn’t mean woman consents to sex. Both types of erection are involuntary reactions and both usually occurs in rape. Man can be raped just like woman. Erection cannot be used to justify it.
