Why is being gay a sin

I always feel drawn to the Bible and Jesus but I can never commit because of all the hate for people. I just don’t understand how Jesus preaches love, it’s one of the main teachings yet this kind of love is wrong. It’s just confusing and disheartening. I’m bisexual so the all loving God sends me to hell for it? I always see people say it’s acting on it that makes it a sin, but how is loving a woman as woman any different than if I loved a man.
