Mc Clary believes all daters should invest the same amount of time conducting these 'self' conversations about personal dating rules as they do primping before a big date.
"Every woman and man should know their boundaries before they start dating, and most of us don't," says Cheryl Mc Clary, Ph D, JD, professor of women's health at University of North Carolina-Asheville.
When Mc Clary refers to boundaries, she's not talking just about the physical boundaries that come with sexual territory. "Emotional wholeness is crucial to the decision process of whether or not to have sex," Mc Clary tells Web MD.
"It depends on how rapidly or slowly things progress." Joan Allen, a relationship expert, finds that baby boomers are far more likely to wait to have sex than younger daters.
