Yes, you're quite right. I should have limited that claim further. Not all modern American evangelicals are ashamed of sex.
Befriending someone does not in any way require that you approve of their choices, though.
I would guess Ruth did not approve of Larry's choice to produce pornography, as it's the antithesis of the traditional (approving) Christian view of sex, where sex is deeply interpersonal and sacred, so much so that it can only function as it's meant to in a long-term, committed monogamous relationship, a.k.a. marriage. Pornography turns an individual's sexuality into a performative falsehood that's then commoditized - few approaches to sex could be more opposed.
