There are guys, my stbx for example, that could not tell you why he is withholding because he cannot understand that first, there is a problem, and second, what was the first question? Even if you try to discuss it you will get utter silence, a dazed look on the face, or, my absolute favorite, " I dunno." LL may never get a real answer no matter how hard she tries to help him articulate what is going on with him.

LL has never gotten an answer other than the standard...
"that's just the way I am", "you know I have a fluctuating libido" oh and "I don't know"
it is very unlikely that h a) knows why or b) will tell me why.
I've offered possible reasons for him to pick and choose from and still nothing...
