Optimally, I prefer the cuck to be a passive presence. It's OK for him to watch (I'd think that's probably the POINT for most). He can even please his wife a bit while I'm pleasing her, but I don't wish to have any sort of man-on-man sexual contact with him (I've read some posts here about cucks wanting to suck the bull's cock. Not into that. Sorry). So anyway, yeah: A passive presence. Also, to second what Ras Clot said above, "Since cuckold husband makes lot of sacrifices & serves his wife to bull, the question should be, what should be an ideal attitude of bull?". Precisely. And the ideal attitude, in my mind at least, would be that of mutual respect. I'm not trying to disrespect anyone, or make anyone feel small (unless that's what they're specifically ASKING for, I guess. And even then, it'd be an act; role play). I think there's plenty of room for all participants to enjoy themselves.
