How can I name my men things that aren't cringe?

Hey guys! My book's set in the modern-ish day in Edinburgh. I have names for all my girls, but struggling with the men. Either the names are cringe, plain boring, or I know someone irl who would be weirded out having like the love interest named after them. I have an Eddie, but that's about it. Here are the three main men:

  1. A genius detective who quit the police force, now returned to solve the case that stained his career.
  2. The 'Captain' (am going to research his position a bit more) - a serious, by the book man who runs a tight ship.
  3. The ex of one of my characters, who launched his writing career following very public unaliving accusations. Good looking, charismatic, and incredibly paranoid that my protag is digging up stuff that needs to stay buried.

Thanks guys. (btw, currently characters have no race as not relevant to plot. just looking for any interesting name suggestions. ty
