Guy that I quoted wrote it first, that's why I replied. As you can see I'm not the only one.
There's also this:
prolactin is believed to influence the likelihood of orgasm in men; high prolactin levels have been associated with delayed orgasm, and low levels have been associated with premature ejaculation.
If you have some basic knowledge, it's caber itself, but rather crashed prolactin that is causing PE and higher PRL is causing DE (delayed ejaculation).
I usually have somewhat delayed, but it's much better than premature.
