A person who by assault or other violence or by threat of a criminal act forces another person to have sexual intercourse or to undertake or endure another sexual act that, in view of the seriousness of the violation, is comparable to sexual intercourse, shall be sentenced for rape to imprisonment for at least two and at most six years.

This also applies if a person engages with another person in sexual intercourse or in a sexual act which under the first paragraph is comparable to sexual intercourse by improperly exploiting that the person, due to unconsciousness, sleep, serious fear, intoxication or other drug influence, illness, physical injury or mental disturbance, or otherwise in view of the circumstances, is in a particularly vulnerable situation.
