How to Accept That Your Child is Gay, Lesbian or Bisexual
To accept that your child is homosexual or bisexual, the first and most important thing is to make sure your child knows that you love them. Focus on being non-judgmental and calm instead of accusatory, and let them know you're proud of them for trusting you enough to tell you. Have an open dialogue where you both can express your questions and concerns. Also, remember that your child is still the same person you loved yesterday, and that you want them to feel comfortable enough to continue being true to themselves around you. Make an effort to learn more about sexuality and what it means to your child's identity. If you're still having troubles accepting your child's sexuality, consider joining a group of parents in a similar situation, or seeing a counselor. Finally, try to help your child gain acceptance by other people in their lives by becoming their advocate to family and friends.
Be sure your child knows that you love them. They've faced struggles too and suffered from internal turmoil—don't make them feel any worse. Imagine their internal struggle when these confusing feelings arose. Talk to your child. Be proud that they trusted you enough to tell you. Today's society is not always accepting. Have an open dialogue where you can both ask questions and share concerns. Remember, your child probably feels a little confused and very nervous also. Focus on being non-judgmental, rather than accusatory, even if the subject makes you uncomfortable. The most reassuring thing you can say is,"I love you, and I am proud of you for telling me." Remember that this is just who your child is. Whether you believe they were born like that or not, you still want your child to feel comfortable enough to feel that they can be true to themselves around you. It's part of their identity, just like their freckles or their laugh. They haven't changed—they're the same person they were yesterday. Make an effort to learn about sexuality. You will be able to better understand your child's thoughts and feelings. This will also give you something to talk about. Maybe you can try catching up with LGBT+ news and pop culture. Try to accept your child. If you have trouble accepting your child's sexuality, consider joining a group geared towards parents where you can talk to your peers about your feelings. Talking to a counselor is another option. Remember that many LGBT+ stereotypes are untrue. Bisexual or homosexual people are not necessarily more promiscuous than heterosexual people, nor are they any more likely to be pedophiles or rapists. Ask yourself: if somebody is gay or bisexual, whom are they hurting? Is a consenting relationship causing any actual harm? Consider what your prejudices (if any) might reflect upon yourself. Why do you feel the way you do? Are you projecting your own fears or hatred onto others? Become an advocate to family and friends. If you present your child with shame or belittle them, your family may echo your attitude. Foster acceptance by showing your family and friends you respect and understand your child. Even acting like you accept something can be a positive step toward opening your mind and true acceptance. Be calm. Don't get angry or tell them that what they have "decided/accepted" is wrong or suggest that it's just a phase and will go away. Remember that your child may be frightened to tell you, or get the feeling that you would disown or hate them. If you believe that your child "chooses" the lifestyle they are living, and could just as well choose a heterosexual lifestyle, ask yourself: Who would voluntarily choose a life marked by fear of discovery, discrimination, and isolation by classmates, friends, colleagues, and family? Would you choose to live in circumstances that made your life a lot more difficult and keep it that way just for the heck of it? Ask your child what their sexuality means to them. For some people, it is not a big deal. It is just one aspect of who they are. For other people, it is fundamental to who they are. It is important for you to understand where your child is coming from. If it is just one aspect of who they are, repeatedly encouraging them to date and talking about their orientation may upset them. If on the other hand, it is fundamental to who they are, being more of an LGBT+ activist and inquiring into your child's dating life may be more appreciated. 
Be sure your child knows that you love them. Talk to your child. Remember that this is just who your child is. Make an effort to learn about sexuality. Try to accept your child. Become an advocate to family and friends. Be calm. Ask your child what their sexuality means to them.
