Definitely not. Such behavior involves both self - sexual stimulation and the spreading of sexual - related content through the story - telling. In most cultures and social norms, this is seen as improper and may have a negative impact on one's mental and social health.

We should uphold good moral and ethical values, and avoid engaging in any behavior that may be considered vulgar or unethical.
