Teach your daughter the art of suprise in defense and she will be fine!!!!! One less "penis" you have to worry about!!!
Or you could have all your biker buddies over with tattoos and spiked dog collars on and a few chains all sitting around on the front porch, flexing their muscles and snarling at the young lad as he walks up the steps. Maybe they should all be wearing a t-shirt with a picture of your daughter on the front and a caption that reads "She's like a daughter to me." "Touch her and I break your face and permantely end your blood line."
Good luck with a teenage daughter. They can be a handful.
I like that idea!! I have 2 daughters that are 15. One is mine and one is the wifes...but they are BOTH considered as mine!!
