As a parrot owner, I’d like to interject for a moment. The first few times a bird tries this on you it may be amusing and you may even think you’re doing it a favour, but after a while the bird will get frustrated because it knows something is amiss. They will then get angry and often bite or turn to self-destructive behaviours like plucking their feathers.

tl;dr allowing a parrot to use you sexually is not good for the parrot and is morally dubious for the human too
