What is the name of this foreign movie I saw on starz when I was a kid?

At least I think it was Starz?? I remember it had to do with this guy that was a gangster or street hood, and he gets thrown in jail, gets raped and finds ne likes it. He turns gay, and tries to hide it for a while. I also remember some guys trying to pick up some girl at a club or bar and one of the guys walks up and puts his hand between her legs and when he pulls his fingers back from between her legs his fingers are covered in mustard... It was a strange film. I was a kid when I saw it so its prob kinda older, thanks NS
