"Even though I normally don't have very gay tendencies, I get turned on a lot by the thought of a male dog taking me. I suppose it might have something to do with my submissiveness."

I could copy that about word for word actually. I'm not into guys really, but I've had the male dog fantasy myself yes. And for me it is definitely part of my submisive fantasies, though it's one that I don't know that I'd ever live out.
