My take, Vito and Michael would have considered having gumars or cavorting with showgirls as a weakness – we all know what happened to Tattaglia, Carlo and Geary.....
Sonny's “sexual excess” made Sonny rash that Sonny still took the risk visiting his gumar Lucy during the gangland warfare, parking his car outside Lucy's apartment block even with buttonmen on guard duty
“Fredo's sexual excess” banging cocktail waitresses two at a time got Fredo slapped around in public by Greene
Could be. After Sonny shot his mouth off at the Solozzo meeting, Vito said, "I think that comedy you play out with that young girl is making your brain soft."
