About 3% of the world's population, regardless of religion, ethnicity, or national government, is homosexual. About 10% are not straight, but fall under one of the many other letters of LGBTQ+. In many situations, it's difficult to come out. Then they can lead a "normal" life. But...
At a later age, people tend to come out of the closet if the situation allows it.
A nice book about this situation is “Te Laat” by writer JAKUM.
Also translated into English as "Too Late." Anyone in this situation can find comfort in this book. Available on Amazon.
