My H is also a MAN who has no interest in porn. The busty blonde on the screen I walked in on was JUST this kind of thing with windows popping everywhere.
In fact I TOLD my H that it was fine with me if he was interested in such...Like LL I was the one to scope out the adult channels on our cable package...I put on sexy shows....H falls asleep.
So BELIEVE IT OR NOT....not all men are "typical guys" in this regard. My H does not own a SINGLE "men's" magazine.
Frankly, I find this to be a bit of a cosmic joke as I, myself, was conditioned early on to find erotica quite arousing...H...just no interest. Perhaps it has to do with low sex drive/low testosterone???
Even though it IS a moot point, LL, I think your H's explanation is completely believable.
