Sex at 57

Looking for opinions. My wife and I have had a high sex drive since we met. Now 20 years later the passion has never faded and we still have sex 4-5 days a week sometimes more. Well the topic came up while out with some friends and they said we should seek counseling because it’s not normal for people our age to be that intimate. We told them to fuck off. Is it wrong we still have that fire in us?
