Interesting question. From a bull's perspective most (but not all) guys want to watch, either in the room or on cam. In the room, hubby can move around, interact and get different camera angles. If he's watching remotely, the cam is in a fixed position, so viewing pleasure is reduced.
Guys naturally assume that when they're out of the room their wife will be wilder and open to doing stuff she would be more reluctant to do in front of him. In my experience, that sometimes happens but more often she's still very receptive when hubby's there. Plus I talk to couples before to see what it is they want and if they're on the same page.
The danger with letting her go with bulls alone is they misread the situation from time to time and try to steal her from you. Again, this doesn't happen every time but from reading the threads here it does seem to be the biggest pitfall. My advice is to vet a potential bull carefully.
At the end of the day, it's what gets you both off. Work towards that and have fun! Let us know how it pans out.
