Dildos are sex toys that resemble a penis and are used for masturbation or in conjunction with sex with others. A dildo can be used to penetrate a vagina, anus, or mouth. Some women enjoy double-ended dildos having different sized shafts for simultaneous vaginal and anal insertions. When worn in a harness, referred to as a "strap-on", it can be used by a woman to either penetrate another woman, or a man during the act known as "pegging". These porn videos are all about dildos, vibrators and other fun sex toys!
