There are various reasons (below are 2 but you guys can probably come up with more) for a woman to stop giving FS extras (as posted "she won’t do any of that stuff anymore") and move to another place where such extras are not required where she can still earn a living — albeit not as much as before:
1. legal For various reasons, perhaps a brush with the law, that she found terrifying, humiliating and expensive and not wanting another. Or perhaps immigration status has expired and she wants to keep a low profile from the legal system by working in a legit place.
For example, I know of one woman who I used to see for many years in flushing who I used to book a 90 minute session for $140 total. 60 minutes involved a spectacular legit massage (the best I've ever had including those given by licensed legit masseuses) followed by a 30 minute extra session. Rooms were spacious, totally private , spotlessly kept clean, heated table in cooler seasons and air conditioned in warmer. Alas, a colleague of hers told her of a place in S Shore Nassau where she could net at least 2X the $ w/o all the massage work — and there she went. All new customers and worked out great for a month. Unfortunately one new customer was an UC and arrested her and everyone in the place for prostitution. She went back to flushing.
2.medical I can imagine certain medical conditions, especially an acquired one, that could cause painful vaginal sex and putting her money maker out of commission for weeks at a time, occurring unpredictably from time to time.
