That's an interesting question. I have noticed a major difference in grooming. Younger subs, say mid 20s to late 30s, are much more likely not have any pubic hair at all! Great for all things cbt related.

Men in their 40s and 50s are a mixed bag of nuts. (pardon the play on words). I have some that are well groomed, and some with beards and body hair like bears.

Men in their 60s and 70s are normally much better groomed. Several having undergone training form one Mistress or another, for years.
