Do you reject these fantasies or do you not like them?

Sounds like something that might come with other situations that happen in life. Were you attracted to any of these women or not?

Arousal can come from any number of things that stimulate a person (males sometimes more so than women), even humiliation can do the trick, so don't worry too much about them. It's not as unusual as you think (having heard quite a few stories from some guy friends of mine who spoke of fantasies akin to yours).
