The advantage of a penetrable mouth
The advantage of a penetrable mouth is that you can choose and alternate between multiple forms of stimulation. This simply gives you more choice and variety, allowing you to switch things up during use. This can help you become less accustomed to each form of stimulation and get bored with a sex doll less quickly.
The disadvantages of a penetrable mouth
A penetrable mouth is often not very deep because there is simply less space inside the sex doll's skull. The opening usually extends no further than 12 centimeters; much more is not possible because the head often has a diameter of no more than 20 centimeters, and space is needed for the skull and neck construction.
Another disadvantage is that the canal of the penetrable mouth angles upward. This is because the canal cannot point straight backward due to the neck construction, with the bolt, positioned there. The mouth canal therefore has to pass over it.
The final disadvantage is that a penetrable mouth on sex dolls is somewhat more difficult to clean. With a vagina or anus, the water can drain out easily; with a mouth, it is more difficult because the water quickly runs down along the rest of the body.
Misconceptions about a sex doll's mouth
The biggest misconceptions people have are also the biggest disadvantages. People often think that the canal points straight backward. However, the mouth canal points diagonally upward toward the brain.
Another misconception is that the canal is deeper than expected; the canal is almost always shorter than the length of the vagina and anus.

How deep is the mouth of a sex doll?
The depth of the canal is between 12 and 15 centimeters, depending on the sex doll's brand and design.
What is a sex doll's mouth made of?
A sex doll's mouth is often made of the same material as the rest of the doll, namely TPE, silicone, or another material such as STPE.
How do you use a sex doll's mouth?
You use a sex doll's mouth in the same way as the vagina and anus. Remember that the mouth is somewhat more compact, the canal often angles upward, and the face often includes delicate makeup, eyelashes, and eyes. It is therefore especially important to be careful and not force the length and space inside the mouth too much. This will help ensure that you do not irreparably damage the face or completely distort the makeup after penetrating the mouth.
