Catherine, pregnant with her first child, paid a visit to her obstetrician's office. After the exam, she shyly began, "My husband wants me to ask you..." "I know, I know," the doctor said, placing a reassuring hand on her shoulder. "I get asked that all the time. Sex is fine until late in the pregnancy." "No, that's not it," Catherine confessed. "He wants to know if I can still mow the lawn."
