For the record, I don't want my daughters to have sex with ANYONE until they are married. I'm not sure if I'll get my wish though...
Maybe you will!
"my daughters(not) to have sex with ANYONE until they are married."
I told my kids that they could always recover from any of their youthful mistakes as long they did not get pregnant or get anyone else pregnant and they did not break any laws.
They both turned out pretty well. Personally I think kids should not be virgins when they marry though I never told mine that. I felt they will do what they will do, the key is not to lose them to mistakes they cannot reverse.
