this is a good question but i don't really have any real pet peeves that come to mind? i'm also afraid that it would just make it seem like i'm punching down on niches lol. there are things that don't do anything for me, specifically, but i wouldn't call them pet peeves, really.

for niches that i'd like to see more, though...! i always wish to see more boys with pussy, first and foremost. i also wish to see more hentai with animal on human!
i think if u go through my gallery u can kinda see what kinda niches i'm really into, and i'd love to see more of them from other people too. thank you for sending this ask in!!!
