You sense of taste is limited to four sensations plus whatever your nose tells you. These are salt, sweet, bitter and sour. All the rest of taste comes from your sense of smell. If you have no sense of smell whatsoever, these four are all you'll be able to taste. Anosmia is the absence of the sense of smell. It can be partial or complete, and can be a result of an injury, illness, or can be congenital (meaning 'since birth'). People with a normal sense of smell confuse the sensations given to them by their tongue (sweet, salty, etc.) with those they detect using their nose. So, people with anosmia also have a limited sense of what many people would regard as taste. http://www.maxuk.net/nose.shtml But it is worse than that. There is scientific evidence that it is virtually 'impossible' to fall in love without a sense of smell. Individuals born with the genetic defect known as Kallmann's Syndrome are unable from birth to smell anything and apparently as a result show no interest in either sex or romantic love. Some people are born with fewer taste buds than others. Some can lose the functionality of their taste buds as well. http://www.tasteandsmell.com/ Is for treating people with taste and smell disorders.

First answer is a nonsense; The "scientific evidence" is based on a book written by a perfume seller that is spreading lies about Kallmann's syndrome. He based in a study of conroversial Dr Money in the 70's, that stated that some men without treatment of testosterone have no interest in sex. The study had.....something like 10 men.......so, no science overhere, and no surprise that men without testosterone have no interest in sex. I have Kallmann's syndrome, my sense of taste is OK, i have felt in love many times in my life, my interest in sex is normal and I live a perfectly normal life. (Normal = healthy and in the standards of my culture)
