is 29 too old for pet play/being a puppy girl

i feel like this questions gonna get hella downvoted cause all my questions on this site do. i really like puppy play and pet play, its very healing and amazing when i do it. im just less than a year away from being 30 and i feel like im gonna get judged by ppl for doing it, like im too old and its just gonna be off putting to other trans women so ive been super insecure about it.
