Exercise the glans penis at the female "entrance" (sexual knowledge adult novel)

Once a beginner inserts it, they are likely to panic and try to get in. Penetration is indeed a great pleasure in sexual intercourse, but considering the exercise of the penis, it is better to view insertion with a playful attitude. When inserting, do not insert it deep immediately. Hold the penis in your hand, place the glans on the vaginal opening, and continuously rotate it at the entrance like an electric massager, patting the clitoris and caressing it. This can make women feel happy and also exercise the penis.
The inside of the vagina is like a hollow, so the penis can provide less stimulation. However, the vaginal opening is concentrated with voluntary muscles, which are extremely tight and can withstand the strong stimulation brought by the penis.
Therefore, constantly rotating in this area is also a good stimulation for the penis. Repeat this game.
It can make the glans accustomed to this stimulation and cultivate a strong penis.
Especially for the stimulation of the vaginal opening, the feeling of wetness can be obtained through the love fluid. When the penis plays at the vaginal opening, you will also get used to the wet feeling. I will tell you later that masturbation is also for exercising the feeling of the penis, but this is only a dry feeling. If you are only used to this feeling, I am afraid you will not be satisfied with the wet feeling of the vagina.
At this time, you may feel that your fingers can bring you greater pleasure, which will cause the penis to feel biased. However, sometimes stimulation through the vaginal opening can correct this deviation.

On the other hand, this game can not only exercise yourself, but also improve women's pleasure. Delaying the insertion time will make women anxious and increase their anticipation. However, when making the other person anxious, you must stimulate the labia and clitoris. This can make the other person more excited and increase the excitement during insertion.
Afterwards, women will definitely praise you and say "you are so awesome", and you will also show your "masculine" confidence.
If you have sex with a condom, doing this kind of stimulation before putting on the condom can cause the melanin in the skin of the penis to precipitate and cultivate a strong penis. "Tapping" with the glans of the penis can also strengthen the skin on the glans area and can also be effective in exercising overly sensitive feelings.
