I have written previously that smelling your partner's sweat works. No wonder millions of men smell the armpits of their women and underarm odor may be a great aphrodisiac. That is also the idea behind pheromones and other substitutes that raise your libido or make you more attractive to others.

We now have research from University of California at Berkeley that proves that women may also want to smell their man's sweat. According to this study led by Claire Wyart, when women sniffed a chemical found in a man's sweat, they found their mood improved and they experienced "total physiological and sexual arousal." The longer they smelled, the effect went up, but just 15 minutes was enough to trigger it.

So when he comes home after a workout, ladies, don't push him to the bathroom; get close to him instead. You will have a much better night in the bedroom.

Scentuelle patch to improve libido

I have written earlier about how we can use pheromones to influence behavior of others - particularly with the intention to make them like us. Naturally, apart from pheromones, there are other alternatives for women if they suffer from low libido. New research in the emerging science of aromachology has shown that a woman's sense of smell is the gateway to increased desire. The Scentuelle patch consists of a complex combination of scent molecules that stimulate the libido by targeting the brain's smell receptors. It reproduces the effect of the body's 'feel good' hormone, dopamine, which controls desire.

"Smell has been the most enigmatic and least understood of all our senses but its importance to our quality of life is incalculable," explains Dr. George Dodd, a biochemist and the head researcher on the Scentuelle development team. A patch for men, using the same technology, is also available.

Simply place the small, transparent patch in a discreet place, such as the inside of the wrist, and smell it regularly throughout the day. Scentuelle begins to work from the first sniff and its effect is cumulative, building to an optimum level after three weeks. Since the patch is non transdermal, nothing enters the bloodstream so there are no side effects. A doctor's prescription is also not required.

So if you think that your partner has lost interest in you, it is something to try.
