It's pointless to judge someone on what they do to with their own private bits on their own time.
At least it's not as public as putting on a loving fursuit.
:l
How often do you see people in fursuits?
And how exactly does it effect you?
It's not like they are raping you.
(Not saying that I would get in a fursuit but you should be open and understand that some people like diffrent things and you should not hate them because of something they enjoy.)
