How do you express your Bisexuality in an environment that will never allow you to?

I am a M 34 that has always deep down known that I liked and was attracted to both men and women ever since I could honestly remember. I have made attempts at coming out in the past 5 years but they have always been very ill received and honestly pushed me farther into the closet. I am married with children and own a small business and am very active in my small conservative community. How do I express myself in a world that will never accept me for it? As many others have said repressing the feelings only seems to make it worse. Why is it so hard to deal with something that I was born with and have no control over. It’s just honestly very frustrating and sad to me.
