I'm not the best person to advise on this as I only have one dog but I see no one has responded to your post yet and you sound quite upset so I thought I'd say something.
I think you'll find lots of people here have had the same experience. He probably is a bit put out but he will get over it.
She may snap at him if he tries to mount her, but she has no other way of saying "No!". Dylan tried to mount his friend Toto and she snapped at him. She didn't bite him or anything. They have to sort these things out like dogs do.
Maybe it would be nice if they slept together but listen to what others have to say. Is prince neutered?
