When you work in medicine, you tend to develop a certain mental compartmentation. You keep in mind that the patient is a whole person, but the parts get focused on as just that, parts. They do, often, blend together. That said, if you are following a particular patient for a particular problem, that "part" is stored in memory so that you can gauge progress. It is called professional detachment.
Now, certain unusual situations or variations do remain in memory, but you don't comment on it, but they may come up in private like other memories do. Certain exams I have done or ...odd variations I remember, even 40 years later, but it is extremely rare that those things are sexualized, and never at the time. As for gossip, it is ingrained about patient confidentiality. Occasionally, you might discuss, in general terms, about something odd happening with a collogue, but it is never dwelled upon.
When that detachment slips or is lost, it is time to hang it up.
