It's a joke and a waste of your time and money. Why do you want that anyway?
Believe in yourself, eh? A little wine will go a long way, if you're looking to relax someone. No one is going to go nuts with sex if they're not already inclined to do so.
Just a girl's point of view!
The "drug" Spanish fly is actually the dried, crushed body of the green blister beetle known as Cantharis Vesicatoria, or the Spanish fly. The drug has been used medically since antiquity as an irritant and diuretic; it was also considered an aphrodisiac. Spanish fly (or Cantharidin) does not work as an aphrodisiac; research done in 1996 by the FDA shows that the drug has no so-called sexual effects. Despite this, the pornography industry continues to have a field day with this myth.
The mechanism of action of Spanish Fly is indirect, and not always effective.
1. It is an irritant excreted through the unary tract, and in a woman some might pissably (pun) end up at opening of the urethra which is between the clit and the vagina.
2. If enough "leaks" out and irritates the pussy, the pussy may lubricate to try and ease the irritation.
3. Then hopefully enough lubrication will spread to labia and clit so that it gets slipperier, which in some woman can enhance/speed/encourage arousal.
Damn scientists, like those looking for the mythical G-spot, can't look beyond the end of their nose, let alone take a systems view of the world.
Have been at a party where pornshop spanishfly (coloured/flavouredwater)was used, it certainly had an effect in loosening peoples inhibitions.
The secret as to why it worked?
Everyone knew it was being used and it was the best excuse to loosen up everyone, men and women.
