Do you see this behavioral pattern displayed more often than other breeds you’ve tried?
I don’t know about other breeds, but I do know about breedings. In my experience, there is not that big of a difference between femboys and non-femboys regarding their asshole displaying behavior.
Do they keep their buns cleaner than my guy?
I have not encountered any femboys with unclean buns ¯\(ツ)/¯
If you don’t have a femboy pet, well I would say that you’re missing out on quite a lot!
