I am wondering if there are other people who are rebooting who have had the same issue as me. The underside of My penis (corpus spongiosum) and glans does not fill very much. And the sides is not very hard
It's caused by tight pelvic floor muscles. It should get better during the reboot. Also, look into getting magnesium supplementation because I believe most of us here suffer from magnesium deficiency to varying degrees.
