You're absolutely right!! My 'holier than thou' sister, mother of three sons, said the same thing. My boys got boxes of the stuff as stocking stuffers and told I don't want you to use this but if your gonna do it, put this on!. My three nephews who were taught to wait, don't do it, don't even think about doing it until your married and sons of my 'holier than thou' sister and brother in law all got a girl pregnant before they were married. Guess those girls should have been smarter than my nephews.
(Oh, and to date, I'm not a grandmother!!)
