Ray was one of five initial suspects named in Kat Moon's affair mystery earlier this year, but he was eliminated from the story after a few weeks.
Despite Ray being innocent this time, Venn told OK Extra that he wouldn't be surprised if the Queen Vic's chef cheated on girlfriend Kim Fox (Tameka Empson) in the future.
Venn commented: "He could so be that guy. Ray's a cheeky chappie and he's very red-blooded. He loves the ladies, so he could stray."
The actor added that he would be interested to see Ray's relationship with Kim become more serious in future storylines.
He said: "I'd like to see more vulnerability from Kim and their relationship moving forward. It would be great to see them start a family. I'd like to see Ray on bended knee proposing.
"I think it would be good for the relationship to really flesh it out. I think that will be extremely interesting."
Venn joined EastEnders last November and made his first appearance as Ray in January.
