Indeed! I've had clients in their 90s! I'm a "well-experienced" lass with life myself, chuckle, looking down the barrel of 60. Ye Gods! I don't feel that old mentally, but I have been slowing down.
My mischievously mature men seem to want more of what I call "carnal companionship" now, kissing, cuddling, chatting, company for outings/trips/movies/lunch/drinks, and not as much marathon bedroom Olympics as when we were more, er, amorously athletic, chuckle. Perfectly natural, and I love to accommodate. My frisky friends and I still enjoy risque romping, however. Keeping the fire of passion stoked and burning helps one stay young at heart, and has many health benefits.
But I am planning on retirement from public pubic relations sometime in 2019, and will only keep in UTR contact with my loyal Fancy fans. I AM too old to take many more risks on new-to-me fellows within the increasingly scrutinized Hobby environment.
