Lust is sexual desire. It isn't rooted in warm feelings familiarity with a special person, it is more of a general attraction for a type of human (sexual orientation). One could say it's impersonal.

Greeks called it Eros, and considered it to be a type of love, although also said it's dangerous.

Christians called it an evil urge that needs to be supressed.

Progressivism tried to be sex-positive, they tried to have more of a "lust is okay" approach, altho other progressives consider women being sexy publicly to be inherently dehumanizing and patriarchal.

I think most normies today think something like it's normal, but it needs to be exclusively channelled into monogamous relationships, after two people developed a deeper bond on other levels. I'm not sure how much of that is possible or expected for casual sex, especially things like one night stands with relative strangers (like at a festival or something). But at the very least you can masturbate in secret (whether doing it to porn is or isn't okay is probably about 50/50).

So is lust okay or dehumanizing? How much room should be given for it to exist and to be expressed? Is it sufficient for humans for connections?
