How do you know if you are a Submissive?

Well, the fact that you have to ask someone suggests that you are. Actually though, it can take a while for people to figure this out. A lot of submissives play the dominant role just because truly dominant people are relatively rare in most places. In general, submissive types wait for someone else to make the first move and expect their partners to make most of the decisions about what happens in the bedroom.
