Of my 5 LTR’s:
1st one no idea, can’t remember and it was before smart phones etc so perhaps not, but probably would have if he could easily have accessed it.
2nd one yes, and admitted it openly. (I wouldn’t tolerate this now but I was young and naive and didn’t have an ethical stance against porn at that time).
3rd one claimed not to at the the time but has since admitted to me he did.
4th one claimed he had looked at it occasionally before we got together when he was at a low ebb, but that he didn’t any more. I’m minded to believe him but can’t no for sure.
5th (and current) one - told me before I bought it up that he had an ethical stance against porn, so I assume he doesn’t look at it, but again, can’t know for sure. I tend to believe him tho.
So on the basis of this highly scientific and exhaustive survey - I would say most men do or have at some point in their life, but perhaps not all? The fact that it is so easily accessible now makes this much more likely. I’m sure a lot of men who would not have dreamt of going to the garage and purchasing a copy of Razzle, will type something into a search engine in a moment of boredom/curiosity.......
