I have found a pdf from HRC that can help adults answer questions asked by children that they don’t fully understand. However, I think this pdf can help people of all ages, please take a look.
Here is a little snippet, I will provide the pdf at the bottom.
What does “gay” mean?
Being gay means that a person loves, in a very special way, someone who is the same gender. For example, a gay man wants to be involved with and love another man. A gay woman, or
lesbian, wants to be involved with and love another woman. Gay people might choose to have a special relationship with someone and share their home and have a family together. Keep it simple. Focus on relationships and family. For older students you could say, “Men who are attracted to and want to have romantic relationships with men.” Or, “Women who are attracted to and want to have romantic relationships with women.” (Note: For more definitions see: What Does Gay Mean? on page C2)
What’s a lesbian?
The word “lesbian” describes a woman who is attracted to and wants to have a romantic relationship with a woman. Or you could say that a lesbian is a woman who wants to fall in love with or is in love with another woman in a very special way. How does someone know if they are gay? At what age do you become gay? Some people may realize they are gay when they are teenagers, while others may not figure it out until they are much older. Being gay has to do with a feeling deep inside of you. (Note: People who are LGBT often say they may have felt different when they were younger but that they didn’t
identify this feeling of difference with being gay until they were teenagers or older.)
Are you born LGBT?
People don’t know for sure. Scientists have not been able to agree about why some people are LGBT. However, most scientists believe that sexual orientation is just a part of who you are when you are born. (According to the American Academy of Pediatrics, “Sexual orientation probably is not determined by any one factor but by a combination of genetic, hormonal and environmental influences. In recent decades, biologically based theories have been favored by experts.”1)
Is it a choice?
No, it is not a choice. People don’t choose to be gay or not. As people grow older they become aware of feeling attracted to others, whether those feelings are for someone of the same gender, a different gender or both. (According to the American Academy of Pediatrics, “Sexual orientation is usually established during early childhood.”2)
