Do not assume female desire has to appear before anything begins. For many women, desire is responsive. It builds after the right signals are already in motion.
A lot of men misunderstand how desire starts in women, so they rush, pressure, or take it personally. Skilled lovers know desire often needs the right conditions before it comes online.
Desire is not always the first step. Sometimes desire is the result of the right rhythm, the right pressure, the right touch, the right words, and enough time for the body to start answering.
