Okay, first thing first, there is such a thing called Genetic Sexual Attraction and it develops, from what I understand, mostly in adoptees.
So, who knows, it could realistically happen, I mean if that is truly what you want.
I should however warn you. That if that was to happen, then statistically it would most likely be a one-time thing.
That might not necessarily be what you want to hear, but it is the unvarnished truth!
