Feelings of jealousy double a man's sexual abilities, according to scientists from the University of Liverpool.
Experts claim that the fear of losing one's partner stimulates the release of hormones in the male body associated with the intensity of sexual intercourse. According to experimental data from scientists, the duration of intercourse doubles if a man experiences a bout of jealousy during intimacy.
What plays a big role is not even the fact of possible betrayal on the part of the other half, but the imagination and speculation of the man himself on this matter.
