How to know what your husband is really looking at on computer?

If you're asking you know deep down he's looking at . If you have a feeling that it's some perverted or illegal o the feeling must be provoked by something you've noticed elsewhere. Aside from looking at the history on the computer I think its time to discuss with him why you feel compelled to know this. He's your husband...if your trust is this poor then maybe you should be questioning your relationship with him rather than just the websites he is visiting.
