What Age Should I Let My Daughter's Boyfriend Sleep Over?

If you make sure that your child is taking the appropriate measures against illness and pregnancy, then age 15 is OK; in fact, that's when I began allowing my eldest daughter experiment with sexual activity on her own. That turned out to be a good outcome.
