Love, Sex And Pheromones: Who's Your True Biological Match?


love, sex and pheromones: who's your true biological match?
Does good sex always translate into compatibility as a couple?
A woman can tell if she's attracted to a man based on his scent, but is this deceptive?

Sexual scent has been studied time and time again. It has been proven that a woman's keen sense of smell can attract a mate—but most relationships and marriages are not true biological matches. A woman's body will react to a man's pheromones if he's a true biological match for her. Her body will begin to release hormones when in contact with a man she has a natural chemical attraction to and blood will rush to her breasts, cheeks, ears and lips. At an unconscious level, the female body understands that this man can produce healthy children.

In 1995, a Swiss zoologist named Claus Wedekind ran a test study called "The Sweaty T-shirt Experiment." He wanted to test a woman's sense of smell to male odors. He put together 49 women and 44 men that were selected for their variety of MHC gene types. The men were given a clean T-shirt and asked to wear it for two nights. The scientist then placed the T-shirts in a box (the "sniff box"). Each woman was asked to smell the shirt. Their task was to sample the odor of seven boxes and describe each odor as to intensity, pleasantness and sexiness.

The results were quite interesting. Most of the women preferred the scent of males whose MHC genes were most different from her own. The study explained that this is because a woman's sense of smell helps her to mate with a person that she's not related to biologically. Two people who share a similar genetic makeup and produce children can cause a host of genetic complications.

Since humans are animals, the natural sexual scent (pheromones) can be powerful, but it's not always the defining factor in how a woman chooses her mate. Humans don't always have sex to breed; in fact, most people have sex for pleasure, intimacy, love and fun. Keep reading...

Why Do Men Hide Their Emotions?


Our brains have two emotional systems that work simultaneously, males seem to use one system more and females seem to use the other system more.  In men as they reach puberty and after their emotional empathy is not the same as a woman's and that boundary is there to prevent men from being influenced by others.  Whereas women take into account ...
