While harnesses can be used by both men and women, the male and female variations of these toys vary. Female butt plug harnesses are designed to accommodate the vulva and ensure that the vaginal area is not obstructed, enabling the wearer to indulge in sexual intercourse while wearing the butt plug.
A butt plug harness can also be used for extended butt plug penetration. In such cases, it is advisable to go for a breathable and comfortable material such as velvet. Polyester and nylon are other materials that are most suited to extended butt plug wearing.
