A 1989 government report states that gay teens are two to six times more likely to attempt suicide than straights their age. Fortunately, there are several good books for understanding homosexuality which also give advice to gays and lesbians and their parents . These are not easy matters to deal with. A common misconception about male homosexuals is that they are all cruising for a quick, impersonal sexual experience. Lesbians seem to develop an orientation towards females for love first, then sexual urges may follow.
Gays seem to develop the sexual orientation first, then the love follows.
There are many theories about the causes of homosexuality. I suspect our bodies are built to instinctively respond with interest to almost any kind of sexual activity. Powerful social training is probably necessary to teach us to avoid certain kinds of harmless sexual activity, such as masturbation, and to scorn other activities, such as sex play with our own sex. Interesting, but that percentage seems too high. They should not feel guilty about who they love and find attractive, any more than a straight does.
