I think most women who aren't sexual know that their man is likely getting his needs met elsewhere.
They rationalize it as:
"So long as he's good to me, comes home at a reasonable time, does his part around the house and makes time for us to have moments together, I don't care what else he's doing"
Soaplands, hostess clubs and other forms of sexwork or sex-adjacent work is big business in Asia.
Loosely related: I saw a Japanese video where the storyline was that a husband's wife was pregnant and he went to a soap land. Turns out the escort he picked at random is his wife's big tt best friend. At first it was awkward for the both of them, but then she put it on him. Throat, cat, movement, expressions, voice. She mastered all the elements and became the last thotbender
