Dual bullet or egg vibrators are vibes that are shaped like a bullet (or egg) and typically attached to a single control panel. This category also contains the triple bullet vibrators (same as dual except with three). They are used to stimulate erogenous zones, including vaginal, clitoral and the anus.

• Clitoral These sex toys are excellent for clitoral stimulation. Use them directly applied to the clitoris, or use a silicone or similar vibrator sleeve and slide it over the dual bullets to alter the sensations you feel when using your bullet vibrators.
• Vagina When using to stimulate the vagina, be careful if you decide to fully insert the vibrator. Typically, the cords on bullets are not strong enough to withstand clenching muscles when attempting to withdraw a bullet vibrator from deep inside the vagina. If this is your intended use, you may wish to use a vibrator bullet wand (a bullet wand has a firm shaft, instead of a thin cord, attaching the controls to the bullet allowing for a more sturdy insertion deep within the vagina or anus). Dual bullet vibrators are perfect to use within the vagina around the outer labia lips and shallowly inserted.
• Anal Sex As with the vagina, be careful not to fully insert the bullet inside the anus. The problem is the rectal wall muscles are too strong and may clench the bullet too firmly and detach it from its cord. Dual bullets are fine to use around the outer edges of the ass and half inserted into the anus. If deeper penetration is desired, again you may wish to consider a vibrator bullet wand.
