Language
The first category of sex toys are those used to directly output or input sexual stimulation. They are mainly: sex dolls , sex toys and vibrators.
Sex dolls are made of materials such as rubber or plastic, and are made to imitate real people as much as possible, like a big doll, usually blown up. Then some imitation vaginas, breasts, mouths, anuses or penises are made or installed in the corresponding parts so that buyers can have "sexual intercourse" with the doll. Some dolls are also added with hair, lubrication or vibration equipment, etc.
Vibrators generally refer to those things that can produce oscillation and vibration effects by electric motors among various artificial products that imitate penises. Some vibrators are also attached with things that vibrate and stimulate the clitoris and anus. The word vibrator comes from the "oscillator" used when mixing concrete. In order to avoid confusion, things used for sex should be called "vibrators".
Sex toys is a broader term that can cover sex dolls and vibrators, and can also include various other artificial objects specifically used for sex.
The second category of sex toys is those items that mainly assist or protect sexual activities. The most common are various lubricants, which can be used directly for penetrative intercourse, caressing those delicate sexually sensitive parts, sexual massage, etc. If condoms are used as "condoms" to prevent sexually transmitted diseases and AIDS, then they can also be counted as sex toys.
The third category of sex toys is a variety of sexy underwear, decorations and cosmetics for the body and sexual organs. The most common are fur or leather bras, briefs, pajamas, garters, chest belts, etc.
