I don’t think McCree would say anything abt other ppls dicks, but I think he’d get off to Hanzo/someone else shaming themselves over being smaller. Imo he’s totally the type to get off to his partner getting off, even with this. Like, Hanzo dirty talking to them both abt how small and useless he is next to McCree’s cock would totes get him riled up. But he himself would never say those things, or even think them, really. Only when his partner brings it up. Bc yeah, every dick is perfect to him
