In a regular day, how many times should a healthy male adult be going to the toilet? I feel like I go far too often

#1 or #2. Depends but minimal urination would be about 4 times / day up to as much as you drink. Normal BM frequency might be up to 7 times/day in some individuals but usually closer to 4 max. Some people only go once every 5 days or so! If you think you are going too frequently you should see your doc to explore volumes / frequency and other associated symptoms.
