Teen years are a time of sexual discovery and learning about yourself. This can sometimes include crushes and sexual experimentation with same sex friends. While these feelings can be strong, this experimentation does not necessarily mean that someone is only attracted to people of the same sex. For some though, this kind of attraction is not just a stage of experimentation.
Homosexuals have feelings of sexual attraction only for people of the same sex.
It is estimated that 10 percent of the population is homosexual. No one knows why some people are homosexual while others are not, but there are two possible explanations. The biological or physical theory is that sexual preference for men or women is determined before birth. The environmental theory is that this preference is somehow developed in early childhood. Because others do not always accept homosexuality, it can be difficult to talk to others about it.
