Background
 I am only in Day 2 of a new “run” of SR and I slept almost through the entire night without wearing a “chastity cup”.  Towards morning, I noticed that I was “grabbing” my swollen package a little too much.  I couldn’t believe how stimulating it felt, but I wanted it to stop!   And that’s when I got the urge to put-on my SD carbon cup and quench the fire!  
The cup goes on easily, like putting-on some underwear. And as soon as I had it on, I had a great relief knowing that my “private package” was again off-limits to my wandering hands. That is the essence of male chastity, whether by an athletic cup or a more traditional cock cage. The feeling is the same.
Male Chastity
 Male chastity is not as much about a sexy, stimulating feeling (although that is a great side-benefit!)   It is about control.  In particular, in my case, it is about someone (or something) being in control of my sexual response, in particular, my ejaculations.  When that control is given-up, strange things happen. At once, I am not in control of my ejaculations.  (Yes, ultimately, in this game-of-one, I am).  But temporarily, I have given up that control to an inanimate object.  And that object I can wear!  That hard piece of plastic, perfectly shaped for my male anatomy, cradles and protects my package perfectly!  If I play by-the-rules, I can’t cheat!
Out-Take
 This piece of “underwear” is only for us men.  Women wouldn’t have a clue how this feels, would they?  So it is ours alone, this “chaste feeling”.  And that thought comes full-circle to the differences between males and females, besides the obvious ones.  I’ll leave that behind for another time, another blog!
