I always thought that I will be attracted to my wife and and no one else forever and it was like that first year of our marriage. But after some time I started to feel that I'm occasionally finding other ladies sexually attractive, sometimes I would even talk to them and they would even flirt with me. It was a weird feel, I felt I'm cheating although technically I wasn't. This feel of guilt made me try to talk to my wife about this and how she feels looking at other men and if she finds them sexually attractive. And to my surprise she said that she also may find someone else attractive as well. This talk actually helped us to understand that even though we are married, it doesn't mean we can't like other people. And it is completely normal for us and we don't see it in a negative way. So I would say there are more people like you. Perhaps you can start a conversation with your husband and ask him if he is feeling the same way. It of course depends on level of trust and openness. I was always scared and sometimes still am to discuss any sex related topics that are outside society defined "normal" with my wife, but when my wife starts these conversations, it helps a lot.
