A sex shop, adult shop or erotic shop is a retailer that sells products related to adult sexual or erotic entertainment, such as vibrators, lingerie, clothing, pornography, and other related products. The world's first sex shop was opened in 1962 by Beate Uhse AG in Flensburg, West Germany, and sex shops can now be found in many countries. Many sex shops also trade over the internet. Sex shops are part of the sex industry.
