Dildos are long and smooth objects suited for gentle insertion into the vagina or the anus in order to stimulate oneself or your partner sexually.
They are to be found in many shapes and sizes. Some of them are made to resemble a penis and others are shaped in a practical way for general stimulation or for stimulation of specific points like the G-spot or the prostate. They can be made stiff, elastic or flaccid.
A vibrator is any vibrating device made for sexual stimulation. Often a dildo with an electric vibrating machinery inside is just called a vibrator.
Whatever your specific use, you should choose a dildo made of 딜도 strong material, it should not have any sharp angles, it should be smooth and the parts of the device should be assembled together tightly and solidly. A flaccid dildo should not be too flaccid so that it does not curl up inside you. A simple and solid dildo is often better than many of the fancily shaped dildos you can get in the market.
If you are unfamiliar with use of dildos, it is best to choose a thin one as a beginners device. When you have more experience, you can gradually begin using thicker sizes. When doing so, you will often experience that the thick dildos do not necessarily give stronger feelings, but rather other kind of feelings, and therefore you will still have use for your thin dildos.
