“Ineffable” means “too great to be spoken in words,” so I’m wondering what you found sexualized about that.

I think you perhaps misunderstood the meaning of some of the words used.

When in doubt, google. I had to google that word myself as a non-native speaker, nothing sexual there.

Bowing down to one's mother ain't something to scorn on. As Jim Jefferies and many others said, show them some proper respect since there won't be another person in your life that will ever love you more, or even equally... at least under normal circumstances
