Answer to Question 1
Although couples have always shared homes in informal relationships without any official ties, living together, or cohabitation, has become more common. About one quarter of unmarried women aged 25 to 39 are currently living with a partner; an additional one quarter have lived with a partner in the past. Couples live together before more than half of all marriages, a practice that was practically unknown 50 years ago. Cohabitation can be a prelude to marriage, an alternative to living alone, or an alternative to marriage.
Answer to Question 2
Human beings are diverse in all ways, including sexual preferences and practices. Physiological, psychological, and social factors determine whether we are attracted to members of the same sex or the other sex. This attraction is our sexual orientation. Heterosexual is the term used for individuals whose primary orientation is toward members of the other sex. Homosexual refers to men and women who prefer partners of their own sex. The transgender community includes individuals whose behaviors do not conform to commonly understood gender norms.
