Pedophilia as a disorder refers to primary or exclusive sexual attraction in adults and teenagers who are at least 16 years old to prepubescent children, so by those criteria it does not include attraction between adults. People might try to fulfill pedophilic fantasies with adults, of course, for instance by seeking out partners who are as young as possible or very young-looking.

In any case the reverse, finding older partners attractive, doesn’t seem to have anything to do with pedophilia. Large age gaps can be troubling for other reasons, though, most notably power imbalance resulting from different levels of experience. There’s a lot of abusive stuff happening outside of the diagnostic bounds of pedophilia, and a lot of ways a relationship can go wrong.

I don’t think your attraction is wrong, still less a disorder. I’m just saying be careful if you decide to act on your attraction. The Scarleteen article Why I Deeply Dislike Your Older Boyfriend, though aimed mostly at cis female adolescents in relationships with older cis men and cis male adolescents, is a good description of some of the pitfalls that may apply to new adults and relationships with other genders as well (cissexism at link).
