When my penis is erect, the head is not nearly as hard as the shaft. Even when I have a raging hardon, and the shaft is hard as a rock, the head is still kinda supple. This is especially true when im on my back - probably gravity makes it worse. I don't have ED or anything; I can get an erection at the sight of something provocative with no problem. But while the shaft is so hard, the head is not. Is this normal? Any other guys get this? I'm worried that a softer penis head is not gonna be as pleasurable to a woman. Is there anything I can do to get the head harder? Thanks.
