Questions About My Faith as a Muslim with Homosexual Feelings

Assalamu alaikum. First, I’m not here to attack Islam or argue. I’m honestly struggling and seeking kind, respectful answers. I truly want Islam to be real. I’ve prayed for guidance, tried to strengthen my iman, read the Qur’an, listened to scholars, and sincerely asked Allah to guide me. But instead of feeling closer, I often feel empty and my doubts grow stronger. I come from a very conservative family, and a huge part of my struggle is that I have feelings for the same gender. My family is completely against it. I keep asking... Ya Allah, why? I hear how people like me are destined for hell, how my community rejects it. I know one day there’ll be pressure to marry a woman, and I’m genuinely scared. I feel like a mistake to my family for something I never chose. It often seems like Islam is just for straight people. A straight Muslim can marry someone they’re naturally attracted to, raise a family, and a man may even have up to four wives under certain conditions. I don’t see any similar path for me. It feels like I’m expected to deny a core part of myself forever, and that makes practicing Islam feel so different from how most straight Muslims experience it. Because of this, I sometimes wonder if my faith is shaped by something beyond my control. Along with tough moral questions-like why Allah allowed slavery instead of banning it outright-I find it hard to be convinced, even though I deeply want to believe. At what point does someone stop being a person who 'rejects Islam' and become someone who genuinely wanted to believe but just couldn’t be convinced? If Allah knows our hearts, how should someone like me understand this struggle? Am I misunderstanding what iman really is, or is belief just much harder for some people? Is Islam actually the true religion? I’m looking for sincere, unbiased answers. Jazakum Allahu khairan.
