Most providers won't see you without screening you. With reviews, screening becomes a lot easier and faster. All they have to do is check out the reviews you've left, and the responses to those reviews.
I am an older person, near retirement age but nowhere near retired. I am though not a techbro so it takes me a while to save for these encounters, so I like to make them count. I do not do this that often and I tend to prefer people who are closer to my own age, or at least not so young as to make me feel weird.
I like to think I am respectful and I appreciate and even celebrate the work you all do as I understand how difficult it must be to offer a service this intimate to strangers.
While I am advanced in years I feel young at heart and I have not given up on the idea of being sexually active. I enjoy pleasing my partner and while I totally understand that the nature of this relationship means a real connection might be difficult I will still try and appreciate the effort that you might put in. I have no illusions though and try to keep things fun while maintaining a realistic perspective.
