Every LTR i have seen (I'm talking like 10+ years) has been where they've abandoned a sex life and are just together from inertia/kids/cultural background that frowns on divorce or where the man is significantly higher quality than the woman. And even then, fewer and fewer woman seem to be ok with the former type of situation.

What can we do if, say, a Chad who's more handsome than you chats up your wife in the office and you see some signs that she might have a crush on him?

Or what can we do if, after a couple of years together, suddenly the wife wants to go on seperate vacations, or starts developing a social life independently of you?

Is it even possible to constantly inspire tingles in a woman, day after day, year after year to the point where this doesn't happen?
