I think the question of whether you're gay or not is not as important as the question of what you are comfortable with. If you feel comfortable dating much older men, then that's really all that's relevant, in my opinion. Society doesn't blink much of an eye at an older man with a young woman, but we all know that a young man with an older woman causes stares and whispers. But that's just society's hangups. All that really matters is whether you are happy or not. If you are, then there's your answer. Peace and good luck to you, friend.
