Most dildos are intended for vaginal or anal penetration and stimulation, whether masturbation or with a sexual partner. Dildos have fetishistic value as well, and may be used in other ways, such as touching one's own or another's skin in various places, often during foreplay or as an act of dominance and submission. They can be used as gags, for oral penetration or for a sort of artificial fellatio.
