Q: Do you always take the wetness of a sub as a reliable or best indicator that she's enjoying it really/you're doing something right??
A: No

Q: Does the cunt ever lie, in your experience?
A: Yes

Everything Euryleia said applies, but I would add that it really applies to all ages. Along with cyclic lubrication, dehydration, and stress the pussy is never a reliable informant. It has it's own agenda.

The organ I want to stimulate is a bit higher and between the ears anyway.
