Sexy lingerie and clothing • Sexy lingerie, uniforms, role-playing clothing and other products not only meet consumers' sexual fantasy needs, but also touch the sensitive nerves of some groups about the commercialization and objectification of sex.

Male function and enlargement products • There are still many products on the market that claim to improve male sexual ability or increase size, including health products, drugs, and even devices.

In general, although these products are hot on the Internet, due to the sensitive content involved, marketing methods, usage scenarios, and after-sales services may become the focus of controversy due to differences in regional laws, risk management, and public moral awareness. When consumers purchase or discuss such products, they also need to understand relevant laws and regulations and public opinion to ensure that they are doing so within the legal and compliant scope.
