Viewing the "Services Offered" part of the provider's profile (requires VIP) all of the services seem to be fairly clear and self-explanatory to me but two of them leave me clueless.

1. S&M - it makes a big difference whether one is the 'S' or the 'M' don't you think? If a provider would be happy to whip you but had no interest in being whipped herself, how would she answer that question?

2. rimming - same problem actually. How would the provider make it known that she doesn't do this but doesn't mind, or even enjoys having it done to her?
