Does Mary McCarthy's The Group stand up well over time?

It's easy to see why Mary McCarthy's novel The Group was scandalous (and popular!) in it's time (1963): right at near the start there's a long chapter in which one of the members of the group, Dottie, (the group comprises 8 Vasser grads newly arrived in NYC) has her first sexual experience, w an older man (Dick Brown!) who gives her much instruction and initiation and when all is said and done so to speak tells her to get a "pessary," I.e., a diaphragm. In the next chapter she does so. All this experience told in close third person, as Dottie undergoes a range of feelings and emotions, not so much of shame though there is that a strong of emptiness and loss - the one question she cannot bring herself to ask her obgyn doc is whether it's significant that he never kissed her.  All of this is rather frank and almost clinical at times and even today seems about as open as a novel can get about sexual desire and sexual politics.  But does the novel stand up well over time? So far - about 20 percent in - a definite yes, keeping in mind that it (or at least the first three chapters) was dated (by 03 years) in its own time - I s definitely a look at a way of life and a social class on the wane and today almost gone. The first chapter, Kay's marriage (she is a westerner from a fairly liberal family and marries Harald  cq, also of the same class and beginning a career in theater - tho they live modestly and plan to have no children they obviously are counting on some family $, tho no parents are invited to the unconventional wedding. We meet, sort of, all 8 women at the wedding tho it's hard to keep them each in mind and distinct. The novel begins to take shape in ch two as MmC narrows the focus to Kay and Dottie. I suspect others will share the spotlight in later chapters, each of which is like a drama in miniature, all working together to evoke a time and place and way of life - gone.
