John
A man who is a customer of a sex worker (SW). Since sugar relationships are different than prostitution (see the wiki on Is Sugar Dating Prostitution?), SDs are not Johns.







Is sugar dating prostitution?
No. Sugar arrangements borrow some of the features of both traditional dating and escorting. It is distinct in itself as a lifestyle choice and stands on its own. While sugar relationships almost always include sex, they also normally include emotional and non-sexual components (e.g., experiences) that are far more similar to vanilla dating.
From a legal standpoint, no news articles have been found covering a solicitation arrest (let alone a successful prosecution) based on a sugar relationship. This is also an argument to follow the recommended SLF best practice of having a platonic M&G prior to your first date, which is a clear differentiator between sugaring and escorting.
Note that there have been prosecutions for solicitation of underage girls, so if you're having an M&G with a young-looking SB, you should verify that she's at least 18 by asking her to show her birth date on her government-issued ID, perhaps while she covers the name with her thumb to preserve her anonymity.
