Strap On Dildo

A strap on dildo is designed to be worn during sexual activity and typically comes with a harness. The advantage is that it can be used with a variety of dildos, with different shapes, functions, and colors, enhancing sexual pleasure during intimate moments. However, strapless dildos use an egg shaped ball to secure the dildo in the vagina or anus, eliminating the need for a harness.
They are ideal for lesbian or male-female role-play and are a must-have for BDSM enthusiasts. They can also be used for solo masturbation. 

Benefits of a strap-on dildo:
Hands-free:
The advantage of a strap-on dildo is that it can be secured around the waist and legs with a harness.
The most basic form of a double-strap harness is similar to a thong. It's easy to put on and stretchy, but size restrictions may apply.
A three-strap harness allows for self-adjustment, so it can accommodate large sizes.
How it's worn: One strap wraps around the wearer's waist, but instead of a single strap between the legs, two straps are placed around each thigh, connecting to the first strap near the front. This secures the dildo and makes it easier for the wearer to adjust the size. The leather and fabric material provides stability and comfort.
The advantage of a strapless design is that it can be used alone or with a partner for deep penetration, and it's more comfortable without the need for a harness. Strapless models also offer a vibration mode for a more synced experience.

Role swapping:
A wearable dildo is crucial when partners want to switch roles during sex. They can be put on beforehand without disrupting play, and they don't need to be removed before continuing. Many couples find role swapping a way to feel more in control during sex, which can greatly enhance pleasure and provide both psychological and physical stimulation.
