Reduce refractory period?
I don't think so pal ...
Nature built that period in to force you to talk to her.
Suck it up!

In biology and psychology, the Coolidge effect is a phenomenon—seen in nearly every mammalian species in which it has been tested—whereby both males and females exhibit continuous high sexual performance given the introduction of new receptive partners
The original experiments with rats followed this protocol: A male rat would be placed into an enclosed large box with four or five female rats in estrus. He would immediately begin mating with all of the female rats repeatedly until eventually exhausted. Although the females would continue nudging and licking him to continue, he would not respond. However, if a novel female were introduced to the box, he would become alert and find the ability to mate once again with the new female. This phenomenon is not limited to Rattus norvegicus. It is attributed to an increase in dopamine levels and its subsequent effect upon the limbic system.
Human males experience a post-ejaculatory refractory period after sex. They are temporarily incapable of engaging in sex with the same female after ejaculation and require time to recover full sexual function. In popular reference, the Coolidge effect is the well-documented phenomenon that the post-ejaculatory refractory period is reduced or eliminated if a separate female becomes available. This effect is cited by evolutionary biologists as a reason why males are more likely to desire sex with a greater number and variety of partners than females.
While the Coolidge effect is usually seen demonstrated by males—that is, males displaying renewed excitement with a novel female—Lester and Gorzalka developed a model to determine whether or not the Coolidge effect also occurs in females. Their experiment, which used hamsters instead of rats, found that it does occur in lesser degrees in females.
Ethologist Frank A. Beach is credited with naming the "Coolidge effect" in 1955, after one of his students suggested the term at a psychology conference. He attributed the neologism to:
"... an old joke about Calvin Coolidge when he was President... The President and Mrs. Coolidge were being shown [separately] around an experimental government farm. When [Mrs. Coolidge] came to the chicken yard she noticed that a rooster was mating very frequently. She asked the attendant how often that happened and was told, “Dozens of times each day.” Mrs. Coolidge said, “Tell that to the President when he comes by.” Upon being told, President asked, “Same hen every time?” The reply was, “Oh, no, Mr. President, a different hen every time.” President: “Tell that to Mrs. Coolidge.”

I like that last paragraph with the joke! That was funny!
From what I understand, after you orgasm, your dopamine levels take a hit. Because dopamine is the main antagonist to prolactin (which is responsible for breast milk and turning off sex drive), while your dopamine is low, your prolactin is high. Your dopamine then begins to rise again (which will begin antagonizing the excess prolactin production), and the time required to get your prolactin levels back to optimal range is your "refractory period".
Pramipexole, Cabergoline work the best from what I understand, as they are pharmaceutical dopamine agonists (emulate dopamine), so it is possible to inhibit prolactin to ZERO!
P-5-P, L-Dopa, and Vitex (Chaste-berry) are the best OTC for prolactin control (from what I hear, I've never tried any of these). Dopamine is made from L-Dopa, but I don't know how the others work. Hope I helped! As always, ask around, I'm not a professional!

Being young helps. I don't know about refractory period but MP gives me morning wood like crazy.

Mucuna Pruriens contains L-Dopa, but in small quantities (and L-Dopa is a precursor to dopamine: see here: http://en.wikipedia.org/wiki/L-DOPA). If you supplement with it, the L-Dopa quantity needs to be concentrated. Also, it appears vitamin B-6 is essential for the conversion of L-Dopa to dopamine, so supplementing with it (or P-5-P I think may be substituted) may also be necessary. The increase in dopamine should reduce prolactin, thus decreasing refractory period, although there would be a biological limit to this effect, depending on the quantity of the enzyme necessary to convert the L-Dopa to dopamine, thus proving why there are pharmaceuticals to bypass this limitation.

I have used bromocriptine in the past for the same reason and suffered a loss of (muscular) size and strength on that also.
