Respectfully, your argument doesn't hold water because it doesn't look like you understand what being/falling in love is. Sexual attraction is 70%-90% visual appearances and mostly biological, but falling in love is not about sexual urges, it's about happiness. We fall in love with the person that brings happiness and joy to our life by merely spending time together, not necessarily the one we want to ram our genitals into.
Most people pursue partners based on sexual urges, sure. But falling in love is a whole other game, and they don't go hand in hand.
