Which Gangster Characters Would of Had Gay Relations in Prison?

Tony insinuates to Carlo in Season 6a that Vito isn't the first mobster to be gay, due to other guys they know having served long prison sentences. For that reason they "get a pass" as he mentions to Melfi later in the episode. So which characters do you think Tony could of been inferring to?

My picks are:

Obviously Phil Leotardo, although most likeky unknown to Tony. This is due to Phil's obsessive homophobia and hint of arousal as Vito is beaten to death in front of him. Also, the symbolic shot of him emerging from the closet to murder Vito.

Richie Aprile. His reluntance to get a blow job from the strippers at the Bing, his staring at women's underwear at the mall before being confronted by Tony for the Beansie incident (indicating sexual confusion), and his violent reaction towards the notion of his son being gay. He had also disowned his son for being gay, and seems to only like making it with Janice when he has a gun pointed to her head...Could he also be reliving a prison experience of being sodomized in this manner?

Angelo Garepe and Tony B. Less certain of this one but have heard theories due to the closeness of their relationship and Tony B emotional reaction to Angelo being wacked. Although this could easily be excused as the product of a father/son relationship and Tony B's violent temper.

Ralph Ciferetto. Without a doubt only able to be aroused by women through pain, humiliation, and the use of dildos on his behind. He's often also seen touching other men while Jackie Jr had him pegged as a "secret fag". Lastly, was seen sexually abusing Tracee in the backroom of the Bing with a cop. Despite all that, it seems he never spent time in prison.
