This sounds like fun:

Scientists last week revealed they had successfully tested a nasal spray, PT-141, that sent ‘healthy, normal women’ into states of high sexual arousal.

‘The crucial point about PT-141 is that it directly targets the brain’s arousal centre,’ said Dr Carl Spana, president of Palatin Technologies, of New Jersey.

[L]ast week…Professor Raymond Rosen of New Jersey’s University of Medicine and Dentistry revealed results of the first human trials of PT-141. Sixteen healthy women were given the drug and 16 were given a placebo. All were shown erotic videos, while detectors measured blood flow in their vaginas.

The women given placebos hardly reacted while those on PT-141 had pronounced increases in blood flow – results that demonstrate the drug has potential that goes well beyond its use only as a medical aid, though Spana counselled caution. ‘The drug can only be administered as a nasal spray – which isn’t good for seducers. You can’t put it in a drink and sticking it up a girl’s nose is hard to do surreptitiously, after all.
