How can i make my cockatiel not see me as a mate?

[Phoenixcockatiel]

Hello,
I have a male and a female cockatiel, but my male is fixated on me instead of his acutal mate.
I don't pet him on his back, I don't let him sing to my feet, but he shows all those behaviors and aggression towards me. Is there anything I can do?

Do you want your cockatiels to breed?

Not neccessarily, but I would love them to see each other as mates so they dont get fixated on me because I feel that is unnatural and frustrating
