How can I explain homosexuality to my parents?

Maybe talk about what it means to you to them and get them interested in hearing about it? How about some informative books on it?

This is always quite a difficult challenge, because it always depends on how your parents view homosexuality. If they are homophobic, please take time with them, be patient, and explain and show in a way that only they can understand.

That depends whether your parents are chill about it or not. If they seem like they are then go for it. If they're not, do not saying anything till you are independent have your money because some parents cut their children off and will not give them money for survival. If youre planning to come out then do it when youre 18 or above (the time youre independent and are a lot more financially supported) so your parents can never cut you off and turn you into one of these homeless LGBTQ kids.

Try to sit down and tell them that you have sum thing important to talk to them about and explain the best way possible

I emotionally prepare for the worse and hope for the best. It is so important to have support around coming out and accepting and embracing my identity as one that takes strength to hold.

I am going to assume you are wanting to come out to them. In a short and sweet answer, you should just explicitly tell them you like the same gender and you were born that way. They may respond negatively but in the end, you'll feel much better. Hope I could help :)

You like members of the same sex the same as straight people like members of the opposite sex. Explain that it is not a choice, but you should be proud of who you are.

You're going to have to explain it in terms that they're comfortable with. If they appreciate science, explain it as a natural phenomenon which happens in all animal species. If they are religious, explain it in terms of that. Overall, make sure you do your research and cover areas which they might ask questions about.

I personally explained it to my parents by telling them that I was in love with someone who just happened to be the same gender as me. It is still love :)

You can come out when you are perfectly comfortable with it, though everyone gets nervous. To come out to your parents, you basically say, "mom, dad, I'm gay." Or something like that. But please don't come out to your parents if you know you will get kicked out of the house, get shunned, etc. I want you to be safe.
