Finding a deep, low belly breath helps to downregulate the nervous system. Using this breath will help you throughout your day as well as in bed. This breathing will help you connect more deeply with your partner; you can match your breathing with hers to create a circular connection of profound depth. You can relax your genital region to be able to feel greater pleasure for longer.
This is a foundational exercise/ meditation/ game for all of life. Deep relaxation will help you match your partner's whole vibe, delay or redirect ejaculatory energies, improve blood flow, and drop you into a parasympathetic state.
