I'm glad you asked this, TP, because it gives me the chance to use LL's great one-liner from a previous thread.
Q: What happens when women use viagra?
A: A stiff lower lip?
And while I'm making viagra jokes, I'd like to repeat one I made on that same thread.
Q: What's the scientific name for Viagra?
A: Mycoxafloppin
Q: What's the generic name for it?
A: Mycoxafailin
To seriously answer your question, here's my answer from that same infamous thread. Enjoy.
Viagra is a selective phosphodiesterase inhibitor that preferentially prevents constriction of the helical arteries of the penis, allowing them to dilate and fill up the erectile tissue on demand like they did in their younger days. Viagra was actually first tested as a treatment for angina to (like nitroglycerin, etc.) but the researchers began hearing reports of a particular unexpectedly-stiff side effect in some of their male subjects.
More recent studies with women have shown that Viagra also increases blood flow to the female genitals, but there was no evidence of statistically significant improvement of sexual desire, sexual pleasure, number or intensity of orgasms, etc. so don't go rushing out for it. (there are several other drugs undergoing FDA trials that have real potential, so all's not lost)
...Not to say that Viagra might not work for you ladies. The placebo effect is a mighty powerful thing (remember how the crows convinced Dumbo he could fly with the magic feather?). Placebo tends to have about 30% efficacy across the board in most scientific studies (never fails to amaze me).
Thanks for your great answer, Clozoff. Loved the jokes, disappointed in the medical information. I'd been thinking of working it into a story line, but oh well.
On another hand (one is busy) what do you (or anyone) know about the effect on males given the date-rape drug? Can't recall if the name is ecstasy or rhapsody. Either way, you know what I mean.
I've never heard of "rhapsody", but I know what ecstasy is, and it's not a date-rape drug. Ectsasy is a designer drug with both stimulant properties (like cocaine) and hallucinogenic properties (like LSD). And from what I hear the sensations of sex are extremely heightened with ecstasy.
However, heightened sexual sensations aren't what date-rape drugs are trying to achieve. The low-lifes who use these drugs want to have sex with women who would ordinarily be unwilling and for this you need a strong sedative.
That's why GHB (sorry, don't know the full chemical name) is what they use. It decreases the user's level of consciousness often to unarousable unconsciousness so they can't resist the rape. Respiratory drive is also depressed.
At lower doses, it essentially it puts you into a an extremely labile state as if you're sleepwalking. Another quality that makes it popular with date-rapists is that the user often doesn't recall much of what happened while under its influence. At higher doses you become unconscious, and at even higher doses you can stop breathing and die.
But in regards to sexual performance it decreases arousal and decreases pleasure. It should have this same effect on men. A man taking it would be much like a woman who takes it, but the difference is that a man can force himself on a semi-conscious woman, but the reverse doesn't work (for obvious reasons).
