Do all teen boys have this problem?

Peace be upon y'all. I am having a problem which is that, I am peeing a lot. It may sound funny but like I drink only a little amount of water like 1-2 glass and then I have to pee 5-6 times a day. Don't say to do kegel cuz it makes my problem worse. I talked to the doctor and he said that every male has this problem and he told me some things realed to prostate gland and stuff. I think I should drink more water but I fear that I may pee a lot. It's uncomfortable man like I can't attend lecture properly. In the midst of lecture, I feel this urge and I am just too shy to ask to have a bathroom break and I have to wait until class is over.
