True, but when one of the parties appears obviously young and the other not, people tend to get creeped out by it just the same, and in kind of the same way. As sexual taboos go it's not the worst and the stigma isn't always fair but it is what it is.

I attribute a lot of that to the increasing youth-orientation of modern culture, since "May-September" relationships have been common throughout history, although legitimate concerns about abusive power dynamics and exploitation do sometimes arise in the modern context.
