Stress that it's a positive thing that girls and women menstruate because it's a healthy sign that their uterus is working properly and that they can be mothers one day. This would be a good time to explain that boys bodies practice for being grown up as well they have wet dreams, or nocturnal emissions. That is, when boys are around nine, their testicles begin to make sperm for practice. Sometimes some of the extra sperm come out at night and make a small wet spot on boys pajamas or sheets. Again, stress that it is a good thing, because it's a sign that a boy s testicles are working properly and that he can be a father some day.
Masturbation is completely normal and healthy.
After all, we are sexual beings born with the ability to have an orgasm. It is, however, a private activity that must be done when no one else is around, such as in the bathroom or alone in the bedroom. It's important to stress this to your child in order to prevent possible opportunities for sexual abuse. Sadly, much of child sexual abuse is perpetrated by someone known to the child. If a child is sitting on the couch masturbating in front of a babysitter, for example, this may be an open invitation for some exploitation to occur.
