I think there's a difference here between client and provider. OP, as a client you set your desired parameters. Provided you are clean and not overly-perfumed (we've all encountered people who take it waaaay too far), I think it's your prerogative to groom for your meet as you see fit. Providers OTOH need by default to provide a blank slate to accommodate client preferences, as discussed above. In the west, underarm deodorant marketers have convinced us all that we stink to high heaven without daily (or more) application of their products. I guess the default for providers would include deo, unless otherwise specifically requested by the client, but I think cologne, body oil or other artificial scents are a bad idea, again unless the client has made a specific request in advance.
There are, of course, providers whose brand includes a well-developed natural scent, but I guess that's a niche. This topic is often addressed in the ads of more thoughtful providers.
I'm a scent pig, I love musky pits and asses and bushes and foreskins on a fit, younger guy in an erotic scenario. But context is everything, and same can be off-putting, even repulsive, in a social situation or on the subway or in any other non-sexual setting.
