Son: "Dad, why does love-making makes you feels good?"
Dad: "Just like digging in your nose, it`s feels good, right!"

Son: "Why is it that guys don`t usually feel as good as gals?"
Dad: "Just like when you dig in your nose, it`s your nose that feel good, not your finger!"

Son: "Then why do gals feel bad when they are raped?"
Dad: "If a stranger comes along and digs in your nose, will you feel the same way?"

Son: "When girls are having their menstruation, why don`t they usually want to have sex?"
Dad: "If your nose is bleeding, will you still want your nose to be dug?"

Son: "Dad, one last question ... why don`t guys like to wear condoms when they make love?"
Dad: "Would you want to wear a glove when you dig your nose?"
