The fantasies won't stop.

Hey
So I'm currently 16 days no PMO. I've always considered myself straight but if we're being honest I have some mild bisexual/homosexual attractions. The only way these thoughts were ever expressed is PMO but now I've stopped. I'm in a wonderful relationship with a beautiful woman I couldn't love more but these thoughts and fantasies they pervade my dreams and sometimes my waking thoughts. It includes everything from trans to gay sex. Will these pass with time? I feel like they may have sparked from searching for weirder and weirder porn. I find my GF sexually attractive and we have a good sex life. I'm just worried these fantasies will one day force me to do something that will ruin my life.
