I never ask for a clients age but if I have to guess the youngest was early 20s and the oldest was maybe in their 80s.
My experience, younger clients are looking to try something they've never experienced before. Maybe their first time with a guy, could be they're trying to figure out their own sexuality and I've had guys who wanted to lose their virginity. They're usually pretty sweet and nervous.
I love my older clients. They know what they want, they know what they're doing and they know how to respect other people..
There are plenty of different clients and age in never a factor if the meeting goes well or not
