I have far too many pictures of attractive men on my hard drive to take issue with hetero guys wanting to look at pictures of attractive women.
It's natural to want to look at things we find attractive, other human beings included. It's when it devolves into objectificaton of another person that it becomes a problem. While the visual depiction of women in popular culture does tend to reinforce the longstanding tradition of viewing them as objects for (straight) male consumption first and foremost, it doesn't mean that every man who enjoys looking at an attractive woman sees her or the other women in his life in that way as a matter of course. That can only be judged by how he actually behaves towards women when he encounters real ones.
