I'm wondering, as others here are, what are all the entrapments in which you're tangled at the moment. One of them is your marriage, but people can get out of marriages, especially when they see they don't work. There is such a thing as divorce. You could do that before any kids come into play. Your wife would be hurt probably but no one else would be involved.
But again, is the form of marriage you've contracted also trapped in religion and how the community would consider this divorce? Is shame about yourself another mental entrapment?
One solution, if you have become disenchanted with straight sex (I'm guessing you've had straight sex with your wife), might be to stop having sex with her (even though that might be another kind of entrapment to sort out), and to give her grounds for divorce. You have to look into the various reasons that could give you a divorce. I think in the States there's such a thing as 'irreconcilable differences'.
My perception is probably that you got into your marriage too early, maybe before you had time to 'sow your wild oats' or to get a chance to experiment a bit. Your social circumstances probably made it difficult to express liking for other males, and you just didn't have that kind of opportunity. I know my partner didn't realise he was 'gay' until he was well past his forties, so this can happen, I'm afraid to say, even today.
It would help to know how you came to the realisation that you weren't into women and that you might need to experiment with a man (it doesn't have to be 'men' in general, because as someone said, we're not all sluts). Have you started developing a libido for men, for men's bodies? A distrust of women, or a dislike for women's bodies? A fear of fatherhood?
Someone also suggested a councellor which your marriage would need if you stopped having sex with your wife, because she'd be wondering why you've stopped asking for it, or why she's not getting it when she requires it, especially if she's looking at having children.
Another way of getting things noticed would be to become a bit more vocal about things pertaining to LGBTQ rights and expression. Ask your wife what she thinks as you hear about, or watch a programme on gay rights, or gay pride. Express your doubts about the fixed nature of human sexuality (it is more fluid than some people might allow it to be), express your concern with people who are not treated fairly on account of their skin colour or sexual orientation. You live in the Bible Belt, you said. Are you African American as well? Is the only chance to be gay there to live it on the 'down low' (see that phrase)?

Anyway, we're here to help you sort out your feelings if you can bear to be more open with how this all came about., @
