I don't and I don't really agree with penetrating dogs. At best they tolerate it because they love you, but for me it just feels wrong to fuck my dog when he's not gonna be enjoying it
With zoo my rule of thumb is this: As long as both you and the animal enjoys it, then it's all good
Anal is in a very gray area, so I just steer clear of fucking them in the ass. Now ME getting fucked in the ass? Hell fucking yeah
Because I like chatting about zoo and having people ask questions. People hop in asking how to start or how to do stuff, and others hop in and ask questions and try to understand it. I like that, it's a thing I'm passionate about but sadly isn't accepted in society that much. So chatting about it on here is the next best thing
