Bullets are a versatile sex toy that can be used both by men and women. Initially bullets have been created for external stimulation of the erogenous zones, but their shape allows also penetrating applications:

• Vaginal penetration. Bullets/Eggs are inserted into vagina like a tampon and activated delivering the sessions of vibrations.
• Anal penetration. Anal penetration is especially pleasurable with a love egg combined with stimulation of other erogenous zones.
• Clitoris stimulation. Holding the bullet against the clitoris, the female receive a series of vibrations responding by sexual arousal.
• Nipples stimulation. Nipples are very sensitive spots, stimulation of those creates the added sensations.
• Testicles and penis head stimulation. Men can also use the bullet/eggs for stimulation of their other erogenous zones besides anus and prostate.

All these methods can be applied during masturbation but they can be also used for partner love making as a part of love foreplay or during intercourse. The double egg vibrators are often applied for double stimulation of vagina and anus or anuses of both partners at the same time, or both vaginas during lesbian love making.

In addition, a bullet can be placed on (or built into) the harness of a strap-on dildo to provide the wearer of the strap-on with clitoral stimulation and pleasure.
