Insatiable?

You've brought your woman to a real orgasm; like a gentleman, you allowed her to go first before you allowed yourself the same release. You're pleased with your craftsmanship, and she seems satisfied... But wait, what's this? She's still giving you the come-hither and seems ready for more.
 
The downside: your body cannot go again. Instead, your eyelids remain heavy; your muscles, relaxed; and your pillow urges you to sleep. So if you're going to maintain your self-respect about your sexual prowess, or if you want to keep your woman as happy as you can, you've got to do something.
 

Science Says “No”

The vast majority of guys experience an unbreakable span of time after an ejaculation called the “refractory period.” During this time, the body remains physiologically incapable of ejaculating, but can sometimes achieve an erection. The refractory period varies from male to male, and the duration generally increases with age. Women can experience it as well, especially when they fail to become aroused by further sexual stimulation immediately following an orgasm.

What's Going On?

The refractory period is not completely understood; however, one school of thought blames the issue on an abundance of oxytocin and prolactin combined with a decrease in dopamine. Another school of thought describes a temporary change in physiology during which neurological communication between various organs inhibits the systems required to ejaculate. [1]
