1. Get rid of flowery body wash/soap. I don't go overboard with cologne because you (just like a doctor or a CMT) might be sensitive to smells. The flowery body wash not only damn near overpowers my subtle cologne, it is clear I was visiting someone and showering after, because it's not a guy smell.
If it's annoying for me with no SO, I imagine this is crucial for guys who are married or in a relationship.
2. If you wanna massage with oil, please ask first and be prepared to answer if it has a smell. Same concept as the first point.
3. Smiles melt ice. This is a tough one because I value honesty over everything, but if you're not having a good day, I expect for it to not spill over excessively into your professional life. Not asking for fake forced smiles specifically, but I'd expect at least some effort to look like you're not hating your life. This isn't a common concern ofc but it happens occasionally. Not only you feel bad, but I feel bad ghat you feel bad and also feel bad because a session is not great. It's a triple whammy here.
4. Offer something unique what other girls usually don't. It might be easier to say than to do, but nonetheless. The competition can be tough, and doing something unique makes you stand out and differentiate from ton of scripted stuff and routines.
5. [This is my take only] Don't go overboard on makeup and don't run to get fake tits ASAP after your first tour. Some folks like it natural, both makeup and breasts.
