The problem is, women talked... they gossiped... they gabbed... they raved... they flapped their gums about this steamy 50 shades book and decided they were either (a) head over heels for kinky sex/BDSM lifestyle or (b) they decided they thought the book was stupid.
The problem with option a: you don't just decide one day you are into BDSM/kink etc that sort of thing is a lifestyle decision and if you go into it half assed or half cocked... your liable to come out regretting it only having half an ass or half a ... well...
the point being, you dont just tie your partner up and start poking and prodding and sticking things in other things and slapping and tickling and whipping etc. Nor do you normally make a major lifestyle change based solely upon the latest best seller. (or movie or game - otherwise we would all be submarine commanders by now)
the things that take place in those books... these are things which you have to learn to do properly so as to avoid permanent bodily injury, or even death in the process. You and your partner find someone who knows what the hell they are doing, or a group that knows the
ins and outs of this sort of business and you
learn the ropes. (see what i did there?)
I cant think of anything more embarrassing than to have to go to the hospital to have some object removed from some orifice -
unless of course it is being found dead with said object in said orifice.
