Humans are made in the Image of God, and so are destined for our final end as glorified images. Lust is a reduction of this Image into an object of selfish pleasure; such that it's not about the *person* as embodied, but their body per se as the totality of their "person"

It also follows that physical attraction to the beauty of and in a person is not, when rightly ordered, the same as sexual attraction.

We have severe failure here. It is inherently virtuous to admire the physical beauty of a person without combining it with sexual desire.

Sexual desire itself is a good when rightly ordered. This right ordering is more properly focused on the respect for a person as Imago Dei. So here I part with seeing procreation as the final end. I think this is still too reductive - as it makes the value of a person functional

Ie, the value of the Image Dei is about Being/Essence and Existence as the ultimate Good. So sexuality can be disordered even when directed to procreation (if the person is objectified) and rightly ordered without procreation if the Person in honored per se
