If your friends or acquaintances ask you about your beliefs about God or homosexuality, you can certainly answer them. If your friends want more information, they will ask more questions. Don't let what you know about an acquaintance's sexual attractions prevent you from getting to know him or her as a real person. There is much more to other people than the fact that they are attracted to the same sex. All people have the right to decide if, when, and who to tell about things that are important to them.
Some people are very open about their sexuality.
Others may have told only a few people. If your friend or acquaintance has trusted you and secretly told you about his or her same-sex attraction, respect that trust. Do not tell anyone this secret. If you find it difficult to deal with what you've been told, learn more about same-sex attraction. If you need to talk to someone else, find someone who does not know your friend and who is not likely to cross paths with him or her, and ask general questions without using a name or other details.
