Hello

I read your post and honestly "didn't had a good impression" about it

I don't think it is necessary wrong to be aware of some possible human cognitive processes like the "fatherless" one you're talking about

But:
-It's not obvious that just because a person get into a relationship with a much older one, than she/he is looking for a parental figure
If this happen (possible), then it seems there is not a very healthy situation for a love affair

-just because 19 is really young, this does not allow objectification or controlling behaviors by older people

In conclusion,
I would just recommend you to act responsibly and possibly consider the thoughts you're having about the relationship scheme are not really ok
If you are talking about it maybe is because you already feel you should take a step back
