Banana upward left curve here, wish I had the downward curve @ newmember712, the position determines the spots I hit. In doggy, my curve allows me to get past the cervix into the posterior fornix , which she enjoys the stretch & light pressure sliding past the cervix because it curves away. In missionary or any facing positions, the curve is directly into her cervix and that needs to be very delicate or will result in an instant tap out or position change demand. We use 2 or 3 ohnut rings depending on how intense the session is to walk that fine line of fun/not fun.i have an extrem curve downwards…..captain hook cock
