I agree with SD on this one. I also don't have a problem with porn, so looking at a few racy adds on an internet site wouldn't mean too much to me unless there were other problems.
I think I'd be pretty pissed off if Dazza had been watching porn all day instead of doing a tidy up around the place while I went to work. If I was coming home to a hot meal and a clean house though I'd probably ask him to show me what he'd found.
