I know he’s been in relationships. He dated and then married to Videl. But what if he didn’t find someone at school? What if there were alternatives for him?
Honestly it'd make no difference as Pan isn't a difference maker and Gohan is perfectly content without a romantic life. People here should take notes.
No Pan, so Beerus would have destroyed Earth. If the Earth had escaped somehow, maybe he would have started dating Cocoa Amaguri if you want to count fillers.
