Completely Boxer Crazy
This type of thinking is a little outdated.Mounting has nothing to the urge to "dominate" things or people. And more times than not it has nothing to do with mating either so neutering won't necessarily help either. It's usually an adolescent response to being over excited or not knowing a full range of social skills.
OP, please don't swat your dog as suggested - if you want him to stop doing what he's doing now, then teach him what you do want him to do instead. He sounds like a typical teenage boxer - so if you know he gets excitable around the same time every night then turn it into a training session before the behavior starts. Find some short fun things to do with him that will exercise him mentally. There are some great ideas here:

From my understanding though, mounting can and usually is a dominance thing. May not be sexual as in trying to mate, but is trying to show the other who is boss and neutering can lessen this because there is no drive once they have been neutered? I have not heard it being an over excited reaction? But again I do not know everything and I'm also not a dog behaviorist so maybe I am outdated.
As for swatting, this is always a last resort for me and I do not just go around swatting my dogs. I try my best to be as positive as possible, but sometimes a swat on the butt in is order. i.e. when Jeresy is taking a can of tuna off of the counter right behind my back and the regular commands or get down, no, and stomping the floor are not working. This is just my opinion and I know many many people do not agree with me and every dog and owner are different, just like every child and parent are different. I kind of think this is very close to the whole do we spank our children or not thing.
