Why not teach them to stand up for themselves and say "this is MY body...these are MY dreams...this is MY life. First you must get to know me, demonstrate to my satisfaction that you are a person of character AND that you're capable of earning a living. Next you have to convince me that you want to be a part of my life (and me to be a part of yours) until death parts us. THEN we'll talk about having sex. If these conditions are unacceptable to you, there's the door".
That's what "Tired Mom" is trying to do, despite being held up for ridicule by those who THINK they're so much smarter than she is.
I say YOU GO GIRLFRIEND. And I might add, my husband and I are raising our daughter that way as well.
