It happens.
It happens everywhere, but I would think the midwestern US would see a lot of this happening. Lots of social pressure … often fairly simple communities … very structured ways of life.
It must be very tough … I assume you have little way to vent / give an expression to your feelings?
Have you done things with men, to experiment?
I know some married bisexual men, and some who I think are probably “really” more toward the gay end of the spectrum … I have had sex with a few of them.
So … look. I think the main thing, really, is to be sure of yourself. Secure in your own mind. Just quiet reflection can help with that … it’s not all immediate, obvious, simple, exact.
But a step beyond that, would be to talk with people (online, or in particular places in the real world) … Share experiences, insights … ideas? … that can be a great comfort. Some people won’t “get it”, won’t give the best kinds of input. But many will.
Going beyond and into the world of actual sexual experiences is very much up to you.
I send you best wishes from my corner of England.
