Sitbone discomfort is normal for a while. The seat may still be flat, and those butt divots under the sitbones may not have formed fully yet.
Perinneal discomfort is not, and indicates that the seat nose may need dropping, not lifting as you have stated. You need to get the adjustment so that you feel you are sitting entirely on your sitbones, with no significant pressure on the perinneum.
Another little point. As the butt divots appear, you are effectively lowering your saddle position by a millimetre or more, and you may need to increase the height of your seatpost, and move the seat forward on the rails by a similar amount.
Finally, how is your core strength? Maintaining a posture so that you are on the sitbones and with no pressure on the perinneum requires a degree of core strength -- abs and back muscles. You also should have minimal pressure on your hands. The principles apply to all saddles, not just Brooks'.
