How much beer is too much beer?

My father keeps telling me I’ve got a drinking problem but I don’t think I do! I’m curious to what others think. I’m 25/M and am what I would call a ‘binge drinker’. I Drink 2/3 times a week but only ever beer, roughly 10-15 pints each time so i’d say roughly 25-45 pints a week. I never drink spirits or anything else. I am aware I drink more than the average person but is this amount really such a cause for concern as my father makes it out to be? He’s not a big drinker at all and I think his idea of too much is very different than mine. I just like beer!
