I'm curious whether you can get https://platform.nuenki.app (my deep translation service; I'm just polishing it before release) to run into "too sexual". It's designed to be resilient to that kind of thing, and it works well in my testing, but maybe you have some better "stress test" content than me!
I don't use hosted AI much. But one of the reasons I like AI is that I can ask it something like "Hmm I don't like how this sounds, can you formulate it another way, more colloquial?" and it'll take that into account. Or what I often get is that it translates "you" to singular when I need plural and vice versa. In most languages that differs but not in English.
