Hi Ethan, and welcome to the board!
You ask, "Are there Gay JW's?" According to the society one cannot be gay and a JW. Whether the society is correct or not is not something I will argue on since I don't think this is what want to hear. Taking the Bible into consideration is more ambiguous since there are various interpretations on how you look at scripture (read THE GOOD BOOK by Peter Gomes, it's a very good, scholarly, unbiased look at the Bible's view of homosexuality).
Personally, I'm 23, and like you, I've known I was gay since I was very young. Also, like you, I grew up as a good kid, and I'd like to think of myself as still that way. There was a point in my life when I was actively going to meetings where I felt like I was coerced into living a "straight" life. I found the contradicitons alarming and I decided to leave. I confessed what I felt to my elder body, and instead of being understood, I felt threatened.
I honestly think that the majority of people in my former congregation don't know what it's like to be gay and growing up as a JW. They aren't homophobic, they just don't understand. It can be a life of self-hatred, anguish, and unfortunately self-destruction. Personally, I couldn't have of it. No matter what my relationship with God is, I needed to live a happy, functional life, one that I couldn't have in my congregation.
I say Bravo Ethan, for having the strength and fortitude to realize who you are despite all the other conflicting emotions you are dealing with right now. surprsingly there are many young gay guys like you who aren't involved with the club scene or the bar scene. If you ever get the chance e-mail me, I'd like to know more about you. Are you still close with your family? Are you out? Do you still pray? Keep in touch....
Preston.
