“Sucking someone’s dick” is often used as a way to refer to someone sucking up to someone else in a way that isn’t explicable unless there were a secret relationship

why would you immediately assume you understand its usage in every case?

so why is sucking dick a thing requiring a secret relationship?

also it seems like a specifically gendered expression, why wouldn’t you say “eating Russian pussy” if you wanted to imply that there’s some relationship

It just scans as homophobic, just as calling trump/elon women as an insult reads as misogynistic.
