Do you think kissing is not an intamate thing between husband and wife?

My husband had a fling with a nother woman, he never had with her (it didn't get that far) but he did kiss her. He says that kissing isn't that inportant in a marriage its the emotional part of knowing the person and being with them. I think kissing is intamate and should only be with the husband. He says men just think that way. So men I want to know from a mans point of view?
