There are a variety of harnesses available. Harnesses may use an O-ring or a Vac-U-Lock system to keep the sex toy in place. The O-ring style is the most popular, as it can be used with a variety of different types and sizes of sex toys. In contrast, Vac-U-Lock systems are only compatible with particular dildos made for this locking mechanism.
There are also a variety of harness styles, including double strap harnesses, G-string harnesses, corset harnesses, thigh and arm harnesses, and a range of underwear harnesses. Those with thick straps and tightening mechanisms provide the greatest control over the dildo or butt plug.
There are many reasons why individuals might choose to wear harnesses. Some lesbians and bisexual couples enjoy wearing harnesses so they can penetrate their partners. Some other people use harnesses and strap-ons to anally penetrate their penis-owning partners. This act, called pegging, allows the receiver to experience a deep prostate massage. Harnesses and strap-ons can also help people enjoy penetration, regardless of erection. Some penis-owners may also wear a harness and strap-on to prolong sex, by first penetrating their partners with the strap-on, and then later with their penises. Some people may also find it erotic to watch their partners fellating strap-on dildos.
Make sure to check your waist and hip measurements and establish your preferred dildo or plug size before purchasing a harness. A harness should also have an opening for the penis if it’s to be fitted with a hollow dildo.
