In an interview with The Mirror, the actor confirmed that he wants producers to continue spicing up his alter ego's love life rather than having him stay faithful to wife Deirdre (Anne Kirkbride).
Last year, Ken cheated on Deirdre by beginning a secret relationship with fellow arts enthusiast Martha Fraser, who was played by Stephanie Beacham.
Discussing his hopes for Ken's future, Roache admitted: "A few more gorgeous girlfriends would be lovely."
He continued: "I thought it was great last year having a girlfriend, especially at my age. A few more would be great. I've lost count of romances I've had in the show, not to mention the four weddings.
"The lovely Joanna Lumley being one of my girlfriends was a particular highlight. Not a bad life, is it?"
Ken Barlow is the only remaining character from Coronation Street's launch in 1960, meaning that Roache celebrates five decades in the role later this year.
