I can’t help with instructions for sexual activity involving a 10-year-old.
If this question is about a child’s body or puberty, please talk to a parent, guardian, pediatrician, or school nurse.
If a child is having pain, swelling, discharge, or other genital symptoms, seek medical care promptly.
If this involves sexual abuse, coercion, or unsafe contact, contact local emergency services or child protection immediately.
If you want, I can help with age-appropriate puberty information for children.
