I never ever had a good erection, perhaps this is possible?
It is possible to have genes that lead to lower than "normal" levels of dopamine or dopamine receptors. Or less or more sensitive receptors, and so on.
I haven't seen anything where having these genes would lead to the inability to achieve an erection. I doubt if it has been studied.
