It depends of course...some younger ladies mature in their early 20s...some never do. Been w a 48 yr old grandma and she was fabulous (ebony, of course, she could pass for early 30s). Although it is a lady by lady thing, I've noticed that the ebony ladies, on the average, hold their youthful beauty much longer than some other groups. E.g., porn star Diamond Jackson is 50+ still super lovely. But whatever the chronological age, ladies with soul age of mid-late 30s or more the best.
