Basic Types of Sexual  Behavior

3. Homosexual Intercourse

Not Persons, but Behaviors

Paiderastia The ancient Greeks accepted homosexual behavior as a normal part of a man's sexual activity and cultivated it as a socially beneficial  custom called paiderastia (literally, love of boys, from pais: boy or rather here: male adolescent, and eran: to love). These love relationships were never seen as obstacles to marriage and fatherhood. (After an ancient Greek vase painting) Staatl. Museen zu Berlin, SPK

Kinsey also recognized that even in one and the same individual the heterosexual-homosexual balance may shift over a period of time. There are men and women whose behavior is exclusively heterosexual at one time in their lives and exclusively homosexual at another time. Some engage in both types of behavior but with varying degrees of intensity. Others begin with an equal erotic interest in both sexes and only gradually develop a clear preference for one or the other. However, this preference may not always remain permanent. Indeed, a person's position on Kinsey's rating scale may change several times over the years.
If it is wrong to divide the population as a whole into "heterosexuals" and "homosexuals", it is just as wrong to call any particular individual a "heterosexual" or a "homosexual". By the same token, it is impossible to determine how many people are "heterosexual" or "homosexual". It is only possible to determine how many people belong, at any given time, to each of the categories on a heterosexual-homosexual rating scale. Questions like "How many homosexuals are there?" or "Am I a homosexual?" do not have a scientifically meaningful answer. In short, homosexual behavior is not restricted to a tiny minority of “homosexuals”, but is also found - to a greater or lesser extent - in many other individuals who do not fit this label.

Therefore, the following sections simply describe the basic forms of homosexual intercourse without presuming that it occurs only between particular persons.
