Years ago I had a metal splinter in my finger a week went by before it started going green I had to go hospital to get it removed.

Point being you could get you wife/girlfriend to some how injected a small piece of metal right in your penis and let it fester and get a infection in it and when it looks really bad go hospital and the chances are they'll remove you cock because of the infection. Job done she and you get what you want with no arrests by the police.
