Some scientists think it is a combination of physical and psychological factors:\n\nBeing ticklish is a complicated trait rooted in our evolutionary past. Two searches, "physiology + ticklish" and "why are we ticklish," turned up a number of articles that helped us understand this touchy, feely human feature.\n\nScientists suggest that being ticklish is our defense against creepy crawlies like spiders and bugs, a physiological response alerting us to a specific type of threat. That is why vulnerable parts of our bodies -- feet, chest, and armpits, are among the most ticklish.\n\nWhile there is no question that being ticklish is neurological, scientists contend that it is also learned. One theory sees ticklishness as a personality-based response to perceived attack. Antsy folks may laugh uncontrollably at the lightest touch, or even without being touched at all, while folks made of sterner stuff won't budge during more aggressive tickle attacks.\n\nIf you close your eyes and try to remain calm while you are tickled, you can decrease panic, reduce giggles, and dull sensation. And, no matter how hard you try, it is nearly impossible to tickle yourself.\n\nTickling satisfies our human need to touch. Robert R. Provine, a professor of neuroscience and author of Quest for Laughter, sees the tickle as a form of communication between friends, family, and lovers, playing a key role in the evolution of social and sexual behavior. He points to chimps tickling each other during play, parents tickling little kids, and lovers tickling each other affectionately.\n\n"If you think the social component is not important," Provine says, "Try tickling a stranger." \n\nSecond link - why we cannot tickle ourselves:

It's a nerve reflex which is unique to you. Some people are ticklish on a specific place on their bodies which triggers a laugh response while others aren't. The same goes for your ear/s, you have a unique nerve ending which triggers a cough response!

I love being ticklish and having women tickle me. It's fun and intimate. If anything, it's a plus.

Ticklishness is a mind set. I turn it off most of the time cos I can't bear to be tickled; an uncle used to torture me by tickling me till I screamed. Concentrate on how light the persons touch is, how it makes you feel, you don't need drugs or creams, just relax into it.

This has been asked here before:\n\nMost of us have a ticklish spot somewhere on our bodies, and it is usually pretty easy to find. For some it's just above the knee, for others it's the back of the neck, and some of us go into fits of laughter if someone grabs our sides. Laughing when another person tickles you is a natural reaction. Scientists have discovered that the feeling experienced when we are tickled causes us to panic and is a natural defense to little creepy crawlers like spiders and bugs. Slight tickles from insects can send a chill through your body letting you know something is crawling on you. \nThat same ticklish feeling sends us into a state of panic and elicits a response of uncontrollable laughter if a person tickles us. It's the moment that you least expect to be tickled and are that causes you to feel extremely uneasy and panicked, which leads to the most intense ticklish feeling. Even if you do know that you are about to be tickled, the fear and unease of someone touching and possibly hurting you causes you to laugh. Some people are so ticklish that they begin laughing even before they are touched. \n\nSo, if someone else's touch can tickle us, why can't we tickle ourselves? Much of the explanation for this question is still unknown, but research has shown that the brain is trained to know what to feel when a person moves or performs any function. We aren't aware of a lot of the sensations generated by our movements. For example, you probably don't pay much attention to your vocal cords when you speak. For the same reason, we can't tickle ourselves. If we grab our sides in an attempt to tickle ourselves, our brain anticipates this contact from the hands and prepares itself for it. By taking away the feeling of unease and panic, the body no longer responds the same as it would if someone else were to tickle us. \n\nBrain scientists at the University College London have pinpointed the cerebellum as the part of the brain that prevents us from self-tickling. The cerebellum is the region located at the base of the brain that monitors our movements. It can distinguish expected sensations from unexpected sensations. An expected sensation would be the amount of pressure your fingers apply to your keyboard while typing. An unexpected sensation would be someone sneaking up behind you and tapping you on the shoulder. While the brain discards the sensation of typing, it pays a lot of attention to someone tapping on your shoulder. The difference in reactions from expected to unexpected is a built-in response that probably developed in early human history to detect predators. \n\nAlthough we are not able to tickle ourselves unassisted, there is a way to trick the brain by using a robot tickler. That's right. With all of the know-how of science and technology, a robot has been designed to allow people to tickle themselves. The same British scientists mentioned above have designed a machine that enables you to tickle yourself by remote control. To use the machine, a person lies on their back with their eyes shut. The robot is located near the person with a piece of soft foam attached to a plastic rod that is controlled by a remote control joystick. When the person activates the rod, the robot will react after a short delay. Even with delays as short as a fifth of a second from the time the person activates the rod until the robot tickled the person's hand, subjects have described the sensation as the same as another person tickling them. So, in a sense, you could tickle yourself with a robotic assistant.

When you are tickled, there is a sense of being threatened. When you do it to yourself, there is no threat.

I laughed when I saw this question... I am almost 30 years old and still cannot keep my composure when I am being tickled.  \n\nIt does not matter where, neck..thighs...underside of the arm...belly...feet...etc.  It drives me crazy.  As soon as people learn about it they use it for their benefit.  I on the other hand, wish I could make it stop.  \n\nBottom line is, you could get me to tell you whatever you wanted to hear by tickling me... or at least.. a well thought out lie......!\n\nLOL\nmandy

Some parts of your body are more ticklish than others because of the sensitivity level of your body.  You may have rough feet and they're less likely to be ticklish, or you may have softer less callused feet and they may be more ticklish

Well, I'm not exactly ticklish there, but if I run my fingers there, it feels weird... Kind of like when my hair tickles my arm... it just annoys me because it's barely there!! :-)

Yes, they're pretty ticklish.  Although the feeling of being tickled is nice, I don't being tickled unless it's a precursor of intimate things to come. It's just tooooo frustrating...
