I think that lusting after other women is a mistake but I do not feel there is any harm in looking. However, I disagree with a portion of what she says because I am in relationship that both my girlfriend and I both look at other people, but the difference is that we are both secure enough and have established boundaries(look, but no touch)to where it does not create a problem. I think it depends somewhat on the person you are with, but for the most part as my grandfather would always say" I'ts O.K. to window shop but you better be sure you can pay the price tag(or live with the results)before you touch the merchandise".
