I'm not really worried about yiff anymore.  I'm married to a non-furry and honestly, I'm pretty happy with her.  Now being a non-furry and all, she naturally doesn't get the fandom, but she respect it, hence I respect her decision not to try to understand it.
So I guess I can say, I'm a non yiffy fur, even if I do have the stuff on my computer kept their for when I go out to sea.
