Anyone know? I think 💭 I am just now hitting my primetime. I will be 47 next month and I have lived & learned to be at a MASTER level. I’m excited to evolve and embrace being an older woman in her prime!

between 29-33 yo

When people ask when a woman is in her prime, it really depends on what you mean. Physically, in terms of looks and stamina, I would probably say 20s.  
.
Emotionally, a lot of women feel more confident in their 30s and 40s. Professionally speaking, i.e. career wise, many women hit their stride in their 40s or 50s, after attaining experience and building on their skill set.
.
A woman can be in her prime at almost any age, depending on what part of her life you are looking at.

My experience has been that women in their 40s, pre-menopause, are the hottest.

At some point woman also ends up becoming washed up and over the top broad.  LOL..  

I agree with some that looks wise it's 20s. But wisdom comes with age. Some of the older women I have been with are much better lovers. I see the 30s as years where women can still hold their own looks wise, but also have learned more and can be better lovers. There certainly are some women that hold up well into their 40s and even 50s, but the older they get, the less of them that hold up well.

Back in my early years, a girlfriend offered anal after we'd been dating 18 months. A civvy lady I dated when we were both in our 50s offered it on the 2nd date.

about the peak of sexual maturity, it's about 30-33.  If you are talking about their sexual zenith as a provider, then experience becomes a factor, which I agree doesn't usually happen until they are 40-ish.  

Over the last year,  I've been with a 19-year-old and a 40-year-old provider.  Both were fantastic in their own right.

but technically a woman’s prime age could be 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, etc etc.
