Should I tell my son that he was an accident?

Basically I have lived a life of a hustler. Screwing people and screwing women. Im trying to get everything straight just in case God has been watching my antics. My first son Frank Jr was never planned and therefore he was a big mistake. I feel it might be best to tell him the truth. It will help clean my soul. I might buy him a nice present as a reward. ps my son is 26 years old. I am not looking for sympathy just friendly advice and love.
