I'm going to go totally out on a limb and say that the only people precieving it as an issue are the people giving it so much time on this thread.
It's not an issue, or rather it is just as much of an issue/non-issue as any other component to a relationship that the IO checks.
Coming from a age gap relationship I find some of the comments here offensive... I am in no way nieve, nor do I think my husband would like to hear theories about how people precieve that he is taking advantage of me. Even if the comments are based on what people precieve that others precieve.
Let's keep to the facts people, and keep personal prejudices out of it.
