What does “LGBT” stand for?

“LGBT” is an abbreviation for “lesbian, gay, bisexual, and transgender.” These terms describe a person’s sexual orientation — a person’s emotional or sexual attraction to other people:

  • Gay” describes a person (either male or female) who is attracted to people of the same sex.
  • Straight” describes a person (either male or female) who is attracted to people of the opposite sex.
  • A “lesbian” is a female who is attracted to other females.
  • Bisexual” describes a person (either male or female) who is attracted to people of both sexes.

How many people in the United States are gay, lesbian, or bisexual?

In general, about 3.5% of people identify as gay or bisexual. But many people feel that they are not 100% gay, straight, or bisexual. Sexual orientation often is described as a “spectrum” or “continuum.” Some people may not identify with any of these labels, and that is OK too. It also is possible to not feel any sexual attraction. This sometimes is described as being asexual.

What is gender identity?

Gender identity is not the same thing as sexual orientation. Gender identity is your sense of being a man, a woman, or other gendered.

What does transgender mean?

Being transgender means having a gender identity that is different from the sex you were assigned at birth (your biological sex). Someone born female may feel that they are really a boy, and someone born male may feel that they are really a girl. Others may feel that they belong to neither gender or to both genders (sometimes called “genderqueer” or “gender fluid”).

What does cisgender mean?

Cisgender is a term sometimes used to describe people whose gender identity is the same as the sex they were assigned at birth.

What makes a person straight, a lesbian, gay, or bisexual?

It’s not known for certain what determines a person’s sexual orientation. Who a person has sex with doesn’t determine their sexual orientation. Sometimes sexual orientation has more to do with feelings of love and care. Many adults and teens have never had sex with a person of the same sex but still identify as gay.

When does a person know for sure what their gender identity is?

Some teens may question their gender identity for the first time during puberty. But most people have a steady sense of their gender starting very early in life, by about age 4 years. If you have felt the same way about your gender identity since you were little or for as long as you can remember, you probably will not change your mind. If you are confused about your gender identity, find support by talking to someone you trust, such as your doctor or other health care professional.

What are some concerns that LGBT teens may face at home, at school, and in the community?

Society as a whole is changing. All states now allow same-sex couples to marry. Many schools support LGBT teens and create a safe environment for all students. Still, bullying in school can be a problem. If you are being bullied, talk to your parents, a teacher, or your principal.

Some communities still don’t accept LGBT people. Although some states have laws that address hate or bias crimes against LGBT people, others do not. Some states don’t have laws that protect LGBT people from job discrimination. As a result, LGBT people may hide their orientation or gender identity.

All of these factors can make an LGBT teen feel anxious and alone. LGBT teens who do not feel supported by adults in their homes and schools are more likely to be depressed. Some LGBT teens cope with these thoughts and feelings in harmful ways. They may try to hurt themselves. They may turn to drugs and alcohol. Some skip school or drop out. Some run away from home. Lesbian or bisexual girls may be more likely to smoke or have eating disorders.

Should I tell my parents that I am LGBT?

This is a question that many LGBT people of all ages struggle with. Some parents are open and accepting, while others may not understand what it means to be lesbian, gay, bisexual, or transgender. Some parents may believe stereotypes about LGBT people. Telling your parents is a big decision. Help is out there if you need it. Organizations and resources that can help educate parents, family members, and friends about the LGBT community are listed in the “Resources” section.

What can I do if I am depressed or just want to talk to someone?

If you don’t want to talk to your parents, you can talk to a teacher, counselor, or doctor. Doctors and counselors keep what you tell them private unless they feel that that you are a danger to yourself or others, or if you tell them that you are being physically or sexually abused. It’s a good idea to ask about what can be kept private before you talk to a professional. There also are web sites and hotlines where you can be anonymous if you need information (see  our “Resources” section).

Are lesbian teens at risk of pregnancy and sexually transmitted infections (STIs)?

It’s very common for boys and girls who later identify as gay to have sex with opposite-sex partners. All teens who are sexually active with opposite-sex partners need to use birth control to prevent an unwanted pregnancy. It also is important to use a condom every time to protect against sexually transmitted infections (STIs).

Girls who have sex with girls can get STIs too. Many STIs, including human immunodeficiency virus (HIV), human papillomavirus (HPV), genital herpes, syphilis, gonorrhea, and chlamydia, can be transmitted (passed from one partner to another) through oral sex. Some STIs (HPV and genital herpes) can be transmitted through skin-to-skin contact. An infection called bacterial vaginosis can be common in lesbians. It can be transmitted by oral sex, sex toys, and genital–finger contact. HPV also may be spread by genital–finger contact.

Do lesbian teens need to see an obstetrician–gynecologist (ob-gyn)?

Yes. All teen girls should have their first reproductive health care visit sometime between ages 13 years and 15 years. After the first visit, a yearly check-up visit is recommended. Transgender teens who have female reproductive organs or who are taking female hormones also need female reproductive health care.

What happens during the first visit with an ob-gyn?

The first visit may be just a talk between you and your doctor. You can find out what to expect at future visits and get information about how to stay healthy. You also may have a general physical exam. You usually do not need to have a pelvic exam at the first visit unless you are having problems.

Your doctor may ask a lot of questions about you and your family. Some of them may seem personal, such as questions about your menstrual period or sexual activities (including vaginal, oral, or anal sex).

You also can get the following tests and immunizations:

  • HPV vaccine—HPV can be passed from one woman to another during sex. HPV infection increases the risk of cervical cancer. Three vaccines are available that protect against HPV. They are recommended for girls and women aged 9–26 years. They are given in three doses over a 6-month period.
  • STI screening tests—If you are sexually active, you may have tests for certain STIs. Most of the tests that teens need can be done by the doctor with a urine sample.
  • A Pap test—All women should have their first Pap test (a screening test for cervical cancer and precancerous cell changes) at age 21 years.

What is safe sex?

The surest way to prevent STIs is to not have oral, anal, or vaginal sex. If you are sexually active, you should practice safe sex to help protect yourself and your partner against STIs. You should practice safe sex whether your partner is male or female.

Safe sex means to

  • talk about safe sex before having sexual contact with a partner.
  • avoid mixing sex with the use of drugs or alcohol.
  • use a barrier method (such as condoms, dental dams, and gloves) when touching another person’s genitals with your fingers, your mouth, or a sex toy.
  • avoid getting menstrual blood or other body fluids into cuts or sores.
  • use a male condom to cover sex toys before use. Clean sex toys before and after use.

If you think you may have an STI or have had sexual contact that may have put you at risk, you should be tested for STIs. Even if you do not think you are at risk, your doctor or other health care professional may screen you for gonorrhea and chlamydia if you are sexually active.
