it can be both sexual and non sexual, such as some scenes including just playing fetch and acting like a dog. pup play can also have dom/sub roles with the dom taking on the role as an "owner"/"master" or if they're a pup too they can be an "alpha".
in relation to BDSM, pups can also be collared by a dominant, with special collars to signify ownership. a lot of pups have a headspace known as pup space which helps with the roleplay aspect and getting into a pup persona more easily.
i identify as a pup and it's usually from submissive side, i love to play and be silly! i love biting i have a chew toy just to do that. i love to play with a dominant but i also like to play with other puppies sometimes. i love being cared for especially when i regress, it's a big part of why i like pup play in the first place. rules/punishments are also really important to me they're something i want to implement more into my life. i also act as a kind of support animal for my boyfriend which i like alot :D
i see myself as a fluffy daschund, but honestly any fluffy black dog counts. i have black puppy ears and a red collar with bones on it which me and my bf got :D i would loveeeee to have a tail one day it's just a matter of finding/making one that is perfect for me, i also have a dog bowl but i really want a personalized one! i'm also pupgender i feel like being a pup influences how i feel about my gender since it's such a core part of me.
