When it comes to most yaoi couples do tu agree with their roles?

Like for Naruto, Sasnaru
Do tu think naruto should be the Seme o the Uke?

There's one pairing that I don't like and it's HaruxRin, why?
because I don't think Rin should be the Uke. He doesn't look like one
in my opinion. Maybe with others because of his hair but come on even in the anime Rin was the seme.
Haru is an uke that's final.

So has anyone ever had this problem?
