With sex, just as with all other aspects of human interaction, tuning into the other person is invaluable.
This allows sex to be a couple in tandem, in harmony, rather than two people solely focused on their own ‘getting’ and paying no attention to each other’s flows, energies, speeds, wishes and signals.
Again, practicing The Boundaries Exercise is great for developing this tuning in ‘muscle’.
Of course, tuning into the other person doesn’t mean just doing what they want. In coercive relationships, those being controlled may do better to tune into their own wishes.
