Everyone's sexual needs and intensity are influenced by various factors, such as personal physique, psychological state, life experience, etc. I cannot directly provide the age group with the strongest demand for girls.
The discussion of sexual needs should be based on respecting personal privacy and individual differences, avoiding generalized evaluations of individuals. If you have specific sexual health issues or concerns, it is recommended to consult a professional doctor or sexual health expert who can provide more specific and personalized advice.
We should approach everyone's sexual needs and differences with an open, inclusive, and respectful attitude, encourage healthy sexual behavior and communication, and provide necessary support and guidance.
