Uh..no, I wasn't a virgin either time I got married...

Especially not the second time...
I did, however, wait until I was 19 to have sex and I married the first guy I had sex with.
I will/do talk to my children and my SD about sex and although I don't think it's realistic to try to make them wait until they are married..I will try but I like to focus more on "once you make that move, you cannot go back" and the whole "true love" thing. It's hard because I tell them they aren't allowed to have sex until they're 30 but I just don't know how to handle the reality of things...so we just do it day by day and keep VERY close tabs on them and keep communication lines open.
