What are the different types (and causes) of ED?

Like any learned behaviors, it can be unlearned. This form of primary PE is psychogenic (as opposed to organic or physical) impotence. (Congenital venous leak is a subset of primary PE and is caused by a congenital venous leak in which the venous drainage system in the penis does not shut down properly.) • secondary premature ejaculation Secondary premature ejaculation occurs when, after years of normal ejaculation, the duration of intercourse grows progressively shorter. Secondary PE is due to physical causes, usually involving the penile arteries, veins, or both. • performance
