[nectlxyq] Sex work and the science of libido

Assume libido greatly affects the performance of sex workers.  If so, and given that some sex work is "the oldest profession", there must be tremendous accumulated knowledge of what affects libido, except buried within the trade and never scientifically published.  (Kind of like how science was done before the Renaissance.)

Stress probably negatively affects libido, so the professions may have very valuable knowledge of how to live a less stressful lifestyle.
