Tuesday Talks - Dr. Ricky Arenson shares his views on the biology of sexes. What makes our relationships last and what makes our relationships happy.

Men and women depend on each other for survival and the continuation of the human race. Heterosexual relationships make up the majority of relationships - media currently seems to want to destroy the notion of a happy heterosexual couple as a basic unit - which it still predominantly is.

Hollywood love - Hollywood shows unrealistic expectations of love and sex. Children learn from movies and movies are not an accurate depiction of what sex and relationships are like.

Dr. Ricky Arenson is the author of 'Women are superior to men'.
