This is a public service announcement. I have always liked Lindsey Doe's Youtube videos because they are full of information and she is a no bullshit zone.
I just found this one and also sent it to my daughters--just in case they didn't already know this. (They probably did because we have had many sexual and physiology discussions and I have sent them many things since they were young teenagers.)
I know, I go where most mothers don't dare to tread. . . .
