No, mine doesn’t get as hard as the CC. The glans is largely described as an extension of the CS and has no Tunica Albuginea as the CC does. The TA is largely whats responsible for the “rock hard” condition of the CC. You can do a google search or a search here for the dynamics of an erection. Pretty interesting, albeit a bit heady with regard to functions and wording. Pressure created within the CC/against the TA is a bit more complex than what one might think, at least that’s the impression I got from it. Not just a simple “balloon effect” so to speak.
It sounds like you possess a normal functioning penis. If so, you may notice a bit of difference in firmness of the glans and CS depending on erection level, but it’ll rarely, if ever come near the firmness of the CC.
