There seems to be a divide between "true" dommes, and provider dommes. That divide carries over to clients as well as the dommes/providers. There have been some threads on here lately that have talked about that, and people have expressed their opinions.
Ultimately you need to decide for yourself how it should work for you, just as clients will decide how they wish to see and partake of it. I think there is also an element of equipment, training and experience that sets apart the "true" dommes from provider dommes. Those who are "fetish friendly" don't really go that extra mile when it comes to a well-equipped dungeon and bondage skills. And those dommes who have invested the time into being highly skilled with bondage gear and assembling a well-equipped dungeon do not tend to offer sexual services. Though this is NOT a hard and fast rule, but the dommes I know (assuming they do sometime indulge the sub with sexual favors) keep it very much on the down low.
Bondage is a common fetish, as is roleplay. I have only seen a very few ads that deal with showers (golden, brown, roman or otherwise). That does not seem to be a highly sought-after fetish, and for the most part I think a lot of people's squeamishness with that sort of thing keep it pretty limited.
