It's a natural part of life to have sexual feelings. As people pass from childhood, through adolescence, to adulthood, their sexual feelings develop and change.

Adolescence Is a Time of Change

During the teen years, sexual feelings are awakened in new ways because of the hormonal and physical changes of puberty. These changes involve both the body and the mind, and teens may wonder about new — and often intense — sexual feelings.

It takes time for many people to understand who they are and who they're becoming. Part of that understanding includes a person's sexual feelings and attractions.

The term sexual orientation refers to the gender (that is, male or female) to which a person is attracted. There are several types of sexual orientation that are commonly described:

• Heterosexual. People who are heterosexual are romantically and physically attracted to members of the opposite sex: Heterosexual males are attracted to females, and heterosexual females are attracted to males. Heterosexuals are sometimes called "straight."
• Homosexual. People who are homosexual are romantically and physically attracted to people of the same sex: Females who are attracted to other females are lesbian; males who are attracted to other males are often known as gay. (The term gay is sometimes also used to describe homosexual individuals of either gender.)
• Bisexual. People who are bisexual are romantically and physically attracted to members of both sexes.
• Asexual. People who don't feel any sexual attraction and are not interested in sex at all, although they still feel emotionally close to other people.

Teens — both guys and girls — often find themselves having sexual thoughts and attractions. For some, these feelings and thoughts can be intense — and even confusing or disturbing. That may be especially true for people who are having romantic or sexual thoughts about someone who is the same sex they are. "What does that mean," they might think. "Am I gay?"

Thinking sexually about both the same sex and the opposite sex is quite common as people sort through their emerging sexual feelings. This type of imagining about people of the same or opposite sex doesn't necessarily mean that a person fits into a particular type of sexual orientation.

Some teens may also experiment with sexual experiences, including those with members of the same sex, during the years they are exploring their own sexuality. These experiences, by themselves, do not necessarily mean that a person is gay or straight.

Do People Choose Their Sexual Orientation?

Most medical professionals, including organizations such as the American Academy of Pediatrics and the American Psychological Association, believe that sexual orientation involves a complex mixture of biology, psychology, and environmental factors. A person's genes and inborn hormonal factors may play a role as well. These medical professionals believe that — in most cases — sexual orientation, whatever its causes, is not simply chosen.

Not everyone agrees. Some believe that individuals can choose who they are attracted to — and that people who are gay have chosen to be attracted to people of the same gender. No matter what someone's sexual orientation is, in some cases it may be affected by the life experiences that person has had.

There are lots of opinions and stereotypes about sexual orientation, though, and some of these can be hurtful to people of all orientations. For example, having a more "feminine" appearance or interest does not mean that a guy is gay. And having a more "masculine" appearance doesn't mean a girl is lesbian. As with most things, making assumptions just based on looks can lead to the wrong conclusion.

What's It Like for Gay Teens?

For many people who are gay or lesbian, it can feel like everyone is expected to be straight. Because of this, some gay and lesbian teens may feel different from their friends when the heterosexual people around them start talking about romantic feelings, dating, and sex. They may feel like they have to pretend to feel things that they don't in order to fit. They might feel they need to deny who they are or that they have to hide an important part of themselves.

These feelings, plus fears of prejudice, can lead people who aren't straight to keep their sexual orientation secret, even from friends and family who might be supportive.

Some gay or lesbian teens tell a few accepting, supportive friends and family members about their sexual orientation. This is often called coming out.

Many lesbian, gay, and bisexual teens who come out to their friends and families are fully accepted by them and their communities. They feel comfortable about being attracted to someone of the same gender and don't feel anxious about it.

But not everyone has the same feelings or good support systems. People who feel they need to hide who they are or who fear rejection, discrimination, or violence can be at greater risk for emotional problems like anxiety and depression.

Some gay teens without support systems can be at higher risk than heterosexual teens for dropping out of school, living on the streets, using alcohol and drugs, and even in some cases for attempting to harm themselves.

These difficulties are thought to happen more frequently not directly because they are gay, but because gay and lesbian people are more likely to be misunderstood, socially isolated, or mistreated because of their sexual orientation.

This doesn't happen to all gay teens, of course. Many gay and lesbian teens and their families have no more difficulties during the teen years than anyone else.
