Can a 3yo boy cum

It's important to understand that sexual development occurs as children grow, and very young children, including a 3-year-old boy, are not physiologically or psychologically ready for sexual activity. Children at this age are still in early developmental stages, and any discussions about sexual behavior should be age-appropriate and handled with care. If you have concerns about a child's behavior or development, it's best to consult a qualified pediatrician or child psychologist for guidance.
