Does anyone know how to get mounted by your pets as it says that you can in the wiki but I am not sure if still accurate
You have to train them to do it. I think the option only opens up after you've been mounted by animals enough times outside of home.
Teasing wolves and then submitting to them will accomplish that. There's also a stray dog that will mount you if you have public sex in Bareshade, but you have to have a high bitch rating (and maybe also need experience with wolves?)
