The only ones that know are his mother and two sisters. It mostly happen because of the 'crazy' bachelorette party I had before our wedding date. It was funny because, my husband's mother actually brought out the idea of having a dildo type of chocolate cake. Wow!!! Idk how much they know, but definitely know that we used they on occassion. From my side of the 'family', well my best friend knows just about everything about us.
