Gay man needs some advice as I start to question….

I first developed a liking for men in high school, and I have been interested in men for the past 20 years. I’ve never had sexual elation over a woman. I have female friends, but I’ve never had that kind of attraction, if you know what I mean. My partner who I have been with for 10 years knows I am questioning and the reason is I have started feeling different around women. So my question has anyone been gay and went back to being straight? I am questioning so much after 20 years and figured I see if anyone else has gone through this. Thanks in advance and please just people who want to help reply.
