feelings of sexual jealousy which corresponds to the 90% disapproval of extra-marital sex. American men also feel more sexual jealousy compared to German men when asked which would cause them more distress: i) a partner having formed a strong emotional attachment with another person or ii) a partner having passionate sexual intercourse with another person.

Different weights are given to triggers of sexual jealousy depending on the culture. In liberal cultures,
