To keep a relationship passionate, a couple must spend quality time together, and as they say about reaching a man's heart through his stomach, food is important. But as everyone will agree with me, by the time you end up cooking a gourmet meal at home, half the passion is gone. Of course you can eat at a restaurant but what if that restaurant was designed exclusively for couples and every dish had an aphrodisiac in it?

That is exactly what the Aphrodisiac restaurant does (or you can buy oysters fed with Viagra). The couple sits on a table that reminds them of a luxurious bed and then the fun begins. Strongly recommended when you are in Los Angeles (10351 Santa Monica Blvd; phone number 310-282-8870). Here is a video.

Women must sniff their partners to improve libido

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.
