Basic instinct
An estimated 30% of men have problems ejaculating at some time in their lives. Coolen is one of the few researchers to study this in lab animals.
"She’s giving clinicians the basic information about what exactly is happening in the brain and spinal cord," says Marcel Waldinger, a psychiatrist at the University of Utrecht in the Netherlands.
He currently treats patients for premature ejaculation with antidepressant drugs such as Paxil and Prozac.
These drugs perform well in what Waldinger calls the "stopwatch test". But they have unwanted side-effects because they act on other areas of the brain, and their impact can last 24 hours.
Determining which chemicals activate the spinal neurons could improve treatments for male sexual dysfunction - or even simulate orgasm.
"It’s wild speculation," warns Coolen. "But if we were to find the chemicals that contribute to the sensation of ejaculation and the pleasure associated with it, we may be able to find drugs that have the same effect."

and think twice about using things like lidocaine (& cocaine) they work becasue they numb the sensation but they will numb your partner too.
