Surely people will do some research and look online for information about any 50 shades branded stuff, and hopefully avoid any cheap or dangerous items if they are serious about having some real (and safe) domination in their own bedrooms. I was glad to see that the article from SFGate mentioned that the type of rope Mr Grey orders in the book may not be the best choice for those who are looking to get into to some bondage play. Not sure I would take the advice given by the hardware store manager either though.
First off, let me clarify that I do not mean all women, certainly there are girls out there that have taken the time to truly listen and understand all the dynamics about men jerking off, however I have not met any. So when I say women do not understand, I mean a majority of the women I have talked to about it simply do not understand male masturbation.
