Even if your partner did find that attractive that would just mean that they, like the grand majority of the population, are attracted to the sexually mature/maturing 16-18 range. Something like 10 years too old to be pedophilia.
This is a statement of fact not a statement of opinion, nor a statement of acceptance or encouragement. I say this preemptively because there are always those commenters who will attack you personally because they’re trying to manufacture outrage. Making it impossible to talk about real world subjects.
TFW you don’t even know what pedophilia is, but decide to have an opinion on it anyways… ^Of course I’m sure there’s a human out there that through some disease or abnormality never went through puberty, and still appear as if they are prepubescent.^
You are, however, correct in that attraction is involuntary, it is not something one is able to control, and can have attraction forced upon them.
