Sexual immorality

I’m struggling to hate sexual sin and have started doubting my love for God. I’ve heard countless times that if you love God, you’ll hate sinning, and I genuinely try my best. However, there’s one sin that I can’t seem to overcome. It may or may not be called lust, but it’s the desire to share my body with another woman. Whenever I hear about sexual immorality, I immediately think of pre-marital sex. Not in a way that involves taking advantage of her, but rather to both of us find pleasure. Even my body is screaming at me, and I’m trying to shut all the sexual desires in my body, but I keep failing. Every day or two, I wake up in the middle of the night just to change my clothes from the filthy nocturnal emissions. God, why did you create my body to function this way and prevent me from using it?
