For you that think your family are too overprotective when it comes to sex, this was my story as a teenager.
Mom: Hi guys!
Me and ladyfriend: Hi mom! This is my ladyfriend: (insert your name if you are female)
Dad: Woho! Good catch son! *claps me on shoulder*
Mom: Dont worry, you guys just go right up and "study" eh ;) eh ;) and we are gonna put the music REALLY LOUD down here! And there is no need to be ashamed of stains nor anything.
Dad: No we understand ;) ;) ;)
Girl: Uh... you invited me just to study right?
Me: Believe it or not I did...
Dad: Yeah you two young ones go study! Remember condom though! ;)
Girl: Axel! WTF?! *leaves*
Me: Mom.. Dad! WTF!? I dont know anything about algebra (not even to this day, and I am almost 30)
Dad: Algebra eh? ;) Next time give her a good "algebra".
Me: Mom tell that moron tha...
Mom: Relax son, I understand that you boys have desires and the next time you take her with you, you dont need to be ashamed or come up with excuse..
Moral: To believe I learned most my ways by having ladyfriends... despite my parents... Mom and Dad overprotective? Good... trust me!
