>>2175914I feel it's pretty nonsense to ask if people have more like that, since I feel that's a given, but to be honest with you, boorus tag this stuff like this (or at least gelbooru does, in my experience). They should all be tagged "no_panties", but the butt peek is meant to be tagged "gluteal_fold", and the definition from the front is meant to be tagged "groin". The "groin" tag is used pretty reliably, though.
To compensate for shitty tagging your best bet is to search "no_panties -rating:explicit". There are a lot of artists who do the butt peek thing casually, whenever they can, but it probably won't be tagged to reflect that at all.
