People love to use dildos that resemble a realistic penis and that is why strap-on dildos for women are so popular. These are very popular with lesbians especially if one of the women wants to simulate having sex with a woman like a man does. Some women even use strap ons to give men anal penetration. This can be popular with mistresses in the fetish BDSM world as well. Some strap on dildos not only focus on the penis the woman is wearing but also focus on vibrating or stimulating the woman wearing the device. Some strap ons contain anal sex toys that are inserted by the person wearing the strapon and some contain vibrators to further stimulate the pussy and clitoris.
