The difference between love and sex is :
Love: Emotional please, joy of your heart, and it brings happiness to your daily day; you need it to have a meaningful life. Without it you feel you have no life and no meaning in life. You need it to satisfy your immortal soul.
Sex: Sexual pressure, joy of your body, it gives pleasure to your body parts that are sensitive. It gives pleasure to your mind, relaxing it and relaxing your every mussel. It is like an exercise you like to do every day. You need it to satisfy your mortal soul. It satisfies your different kind of thirst (Which has no proper words).
But Sex without love is nothing, and is meaningless.
As in many ways love itself is blind,
The same way your sexual desire (Hormones) itself blinds you, blinds your judgment, and consequences.
Love is passive
Sex is active
