I agree sort of with the guys above, at least whilst you’re new. Your first spar should have been properly supervised, and you should have had plenty of feedback between rounds. Same goes for your first 50 odd spars. You should be encouraged and brought into the sport well. That said, this is a fight sport, and to be honest with you I can’t remember the last time I went less than about 95% with a guy who knew what they were doing. You definitely shouldn’t have been in a situation where a guy was going crazy on you, but at the same time, in boxing, you are going to find yourself in the ring with guys who want to fuck you up like you wouldn’t believe. I’ve been in with a guy who had done serious time, covered in tattoos that talked about his various prejudices, and who was literally foaming at the mouth like he was a nutter, and who kept telling me he was going to kill me and fuck my corpse, and other words to that effect. Sparring should be controlled, but it should also prepare you to fight, against any opponent.
So, with that in mind, if the situation happens again, you’ve seen what happens when you try and shelter on the ropes. It does you no good, and gets you a beating. Boxing is about stamping your authority on another man. You need to accept that if you keep backing off, you’re going to get smashed. Ideally you wont find yourself faced with it again. If you are, you can either throw in the towel and survive, or you can step in and smash the fucker. Doesn’t have to be pretty. If he can’t control himself, he has lost the right to your respect. Keep your hands high, and throw hard straight punches. Step in with your head down and catch him with it if needs be, as realistically the guy is not going to catch you with uppercuts at such a ‘green’ level. Seriously, as Irish and Egghead said, this situation shouldn’t arise. If it does, you have to handle that shit and teach the guy a lesson.
