It took me until I was 45 to figure out the things you have figured out at 19. Just keep doing what you are doing, get your education and live your life, those who would tell you what to do aren't you, and don't know what they are talking about. The dubbie view on homosexuality is one of the things that convinced me the WTBTS was full of It. It's not like you chose to be gay, although the WTBTS seems to think you do. It's like saying only blue eyed people can live in the new system, its completely arbitrary. Those who say you should live a celibate life aren't gay, they have a way to express their sexuality with out being condemned, you do not.
Well, You have figured all that out, it's just that you have a few years of cult mind control to overcome. Intellectually you know the WTBTS is just the opinion of a few old farts in Brooklyn, its just that it will take a few years to totally get rid of the feeling that you are doing something wrong, but you will. I hope you have a great life and find a wonderful guy to settle down with someday.
