When do people decide if they are gay?

Who you find attractive and appealing depends on who you are as a person. There are many factors and it can be a very complex issue for the small number who are gender dysphoric or who are dealing with rare genetic conditions, but for most people it comes down to your own thoughts and feelings. Even if there are certain environmental factors during the very first months or years of life, once you pass the age of 2 or 3 (according to some experts) these attractions are fixed and are part of the normal variability among people.
