The finger lock is a technique to stop ejaculation by pressing the so-called ‘million-dollar point’.
·        The million dollar point is located on the perineum, between the back of your scrotum and your anus. If you hit the right spot it will yield slightly to the pressure.
·        With the finger lock you press this point when you are ready to come, preventing semen from flowing through the urethra. In fact you return your semen to another part of the body, where it will be reabsorbed by the blood. This is called injaculation.
·        You press with your index- and middle finger side by side. Keep pressing until the ejaculatory contractions cease.
·        It will push a bit more blood into the penis, so your penis might swell slightly. It may also intensify orgasm.
