What kind of psychology is it for my husband to store unhealthy videos in his mobile phone? This should be a normal psychology. Because everyone will have this kind of demand, but everyone handles it in different ways. This kind of thing can only be seen by adults, and your husband is an adult. It's no big deal to look at this thing, just don't indulge.
