Is being gay or bisexual a sin?

So, this has been something I gave flopped on, going from yes, to no, to maybe, to where I am with, yes it is, but I'm not going to be outspoken about it like I used to be (it was like middle school and upper elementary).

But this is all coming from someone who has bisexual thoughts sometimes, like women will only ever be my #1 attraction and I've only ever dated women. But I sometimes have thoughts about certain men, not even sexual thoughts but just the thoughts you'd have with women, like spending time together romantically.

I recently finished 1st Corinthians and read there in i think 6 (I can't check as I'm in the gym on mobile reddit) that sounded like a condemnation where Paul said that there were even homosexuals in Corinth that had been saved through Christ. However through this past tense it sounds like they are no longer homosexual, and that after they were saved they became straight. For someone like me, I already know about Christ and accepted him so I feel like it would be different, somthing that would dirty me after I've been cleansed. I know a lot of anti-gay things are in the OT and Christiand are more ment to follow the NT but still, it being in the OT makes me feel sick about it too.

But on another side, Jesus doesn't speak about homosexuals (I don't think, I haven't finished the book) so would that mean its okay? Should I take Paul's word or the word of the Old Testament. It's kinda confusing for me.

Also, just a small thing about my belief so nothing gets confused and you can see from my perspective more. I am non-denominational, and I believe through Jesus you can be saved, but not just through words. I think that to be a true believer you have to be a follower too, if you don't listen to God then it's not the same if that makes sense. I just want to know if it would be against God's word as a follower if I ever happened to act on these thoughts.

Thank you so much for reading and God Bless
