Girls today are three times more likely than boys to be non-heterosexual. Why?
At least for humans, this most basic of acts is anything but basic. As the pioneering sex researcher Alfred Kinsey put it, the only universal in human sexuality is variability itself. Within the universe of intimacy and pleasure that sex affords, however, there's a lot of room for error.
Sexual desire in females is both more complex and more fragile than it is in males—less tied to biology, more linked to psychology. It is generally more variable; related to how they feel about themselves, what is going on in their lives, to say nothing of a partner's lovemaking style.
Sexual Orientation is a term used to describe our patterns of emotional, romantic, and sexual attraction—and our sense of personal and social identity based on those attractions. A person's sexual orientation is not a black or white matter; sexual orientation exists along a continuum, with exclusive attraction to the opposite sex on one end of the continuum and exclusive attraction to the same sex on the other.
