The surprising benefits of being blinded by love At what point monogamy began to occur in humans is up for debate. Some anthropologists cite the fact that ancient human ancestors were strongly sexually dimorphic — that males and females were different sizes and shapes — as evidence of non-monogamy. A high degree of sexual dimorphism suggests that there are strong sexually selective pressures on one or both genders. In some species, like gorillas, larger males are more likely to be sexually successful by using their greater size to fight off competition from other males. Sexual dimorphism does not always work this way. Species that use ostentatious displays of fitness, like birds with beautiful plumes and brightly coloured fish, compete for the attention of mates, rather than physically fighting off competition.
Opportunities to do so become even scarcer when it comes to matters of sex and intimacy. There is individual place where men commonly reveal their truth. Abraham Morgentaler understands this. The discussion touches on all matters of sex and intimacy.
