How about waiting until 16? My daughters are not in a high risk group for having sex before 16.
Maybe if you have a daughter that is more interested in getting into college than boys you wait until 18 and let her decide.
That means my daughters would even be able to decide for themselvs while they are still in high school and before their senior prom.
And yes, there are still plenty of virgins at 18 (if they are in a stable family with lots of supervision).
I figure at 18, my daughter can make up her own mind how she wants to live her life.
I do know that most women have sex before they are married these days. However, you do not know my daughters, and I should be able to make the decision about this vaccine before they are 18.
By the way, her chances of getting raped are very slim.
If she did get raped, then she would start going for regular pap smears.
