I've dated mostly non-curly men but that's mostly because statistically they were in greater supply in my area.

I've seen opposites attract just as often.

What I do guess might be true is: if couples stay together long enough they may tend to have merging tastes and shared emotional experiences, such that their facial expressions and body language can possibly mirror one another's. Their faces can reflect all that in things like similar smile lines or other expressive wrinkles in similar places, especially if they stay together long enough to do a lot of aging together.
