Very few people observe their neck, shoulder, back. In fact, these are the parts cannot be ignored. You may hear comments like” the more I look at her, the more beautiful she is. Or she was beautiful on your first eyesight.” Neck, shoulder and back are the ones which make the beautiful feeling last long. And Dudou do contribute a lot on those parts.
Neck, shoulder, back may not stand out too much on the sexy issue. Yes, they just play a fuzzy role ---- subtle, quiet, strong stamina. They are in a roundabout way, low-key manner. They surprise you just as the dumb light itching as the fingertips touch the low volts. That narrow thin sloping shoulder and the curve slide down from the neck to the downstream side just shock, enhancing by the curve of waist to the pelvis. You can see the hip a little bit from the shoulder, not too much.

There is elongated soft white neck, gives her a pleasing appearance. There are right proportion and gentle lines on the back, gives her sexy amorous feelings. There are a slight swell up on the breast but an immediate tight up on the waist,  and a round ball turned up on the butt, give her a long S shape. All these make her the rock.

In "Book of Rites”, Confucius said, "Eat Drink Man Woman, i.e. food and sex, both are big desire of human being.” Indeed it is the views of Confucius for life - a physical but metaphysical one. Every life cannot be kept away from two things: eat and drink, man and woman. One is living issue, one is sex issue. The so-called “eat and drink”, equivalent to people's livelihood while “Men and women” belonging to recreation issues. Life cannot live without these two things.
Gaozi also asserted that: "food, and sex, are just basic instinct!"

Adults also need toys and couples want to have more fun. High-quality adult products make sex more harmonious and satisfy each other more.

The condom is one of the oldest forms of contraception. Its history and use can be traced back thousands of years.
It is believed that a form of modern-day condoms were used by the Egyptians as far back as 1,000 B.C.
The earliest evidence of condom use in Europe are scenes from cave paintings at Combarelles in France. Dated 100 to 200 AD.
The first known published description and trials regarding prophylactic condom use were recorded by the Italian Gabrielle Fallopius in the 1500's. He claimed to have invented a sheath made of linen and conducted trials amongst 1,100 men using the condom - none of who became infected with syphilis.
The origin of the word 'condom' is still unknown. Folklore attributes the invention to Dr. Condom or Conton, who was at the court of King Charles II in the 1600's. It is more likely, however, that the name derives from the Latin 'condus', meaning receptacle.
