Anal String, Butt-String, Anal Plug Thong, A-String – Definition & Differences
Terms such as anal string, butt-string, anal plug thong, plug tanga, or A-String are commonly used to describe a specific category of erotic underwear. While the wording varies, all of these terms refer to the same basic concept.
What these styles have in common is that they are held in place not by a fabric back panel, but by an anatomically shaped element such as an anal ball or an anal plug. This element provides positioning and support, while the visible part of the garment remains minimal or completely open.
The term A-String generally refers to underwear that is equipped with an anal ball. More specific terms like anal string or butt-string describe the fixation method in greater detail. An anal plug thong or plug tanga explicitly indicates that an integrated anal plug is part of the design.
This type of underwear is typically categorized under erotic fashion, lingerie, or fetish-inspired garments. Designs range from minimal and functional to decorative styles featuring jewelry or ornamental details. The primary focus is on structure and visual effect rather than coverage.
