While I make videos rather than drawings, over the years as things have grown (haha), I’ve had to figure out what to tell different people in different circumstances. With partners or potential partners, I am very straightforward about the fetish and making videos, mostly because I’ve always wanted to date people who like me for myself, rather than for who I am pretending to be (people also have different levels of jealousy, and I wanted to make sure a person was comfortable with me doing that before getting involved).
However, with friends and family I tend to be more vague unless I know that the person is kink-friendly and will not out me in ways that could be used against me. Usually I tell people that I either do “video editing” or “edit porn” or “edit fetish content” and I don’t elaborate unless people seem empathetic and genuinely interested rather than folks who seem like they just want to gaze at a spectacle of something that seems weird to them.
In terms of advice for not wanting to be associated with the fetish irl in regards to the other art you create in the same medium, I would probably just try to think of ways you can separate and safeguard your works (both in physical form and on the internet), and for your own safety planning, think about what would happen if xyz found out, so you have a plan for any unpredictable things that arise (this will also help you figure out things you might not be accounting for planning wise). For example, many years ago I had a family member open up a piece of mail (since I share a name with someone else in my family) for a payment from a fetish website that led to a rather awkward conversation lol, but at the end of the day, the world didn’t end either. I’m sure a lot of folks do this already, but even something as easy as using a separate internet browser for your fetish (that isn’t readily accessible on your computer) is a good safeguard.
