You have developed an obsession, which may be a part of Obsessive Compulsive Disorder. You have to take Psychiatrist’s help. You can talk to your husband about your thoughts (i.e. urge to look at people’s sex organs) and may not disclose its origin (i.e. net clippings). You can also tell him that you know that it is called Obsession and it can be treated (from net, of course). I think this is how you can break the barrier and seek Psychiatrist’s help.
