Gay is an adjective referring to those with an enduring physical, romantic, and/or emotional attraction to people of the same gender. This is most commonly associated with gay men, as a gay woman may prefer to use the term “lesbian” instead. Queer and bisexual are also among the terms used for those who are attracted to members of the same gender.
Other definitions/things to note:
There has been controversy surrounding the use of the word “homosexual” to refer to gay people, as it has been considered an outdated term that is derogatory and offensive to many lesbian and gay people. The term ‘gay’ is most commonly acknowledged and accepted.
There is not just one way to experience same-sex attraction, nor is there a set period in life for a person to discover that they experience it. While some may know that they experience same-sex attraction from a young age, it can take others years to figure it out or become comfortable enough with their identity to acknowledge it to themselves and others.
