My biggest question is why do you want to do three passes when you are prone to irritation? The more time you spend with a blade on your skin, the more likely you are to experience irritation.
The common advice for sensitive skin is to use a super mild razor. I think that is bad advice. A super mild razor will make you add excess pressure, excess blade buffing, and excess passes. That means your skin is going to spend a lot more time with the blade on it and you will get more irritation. This is partly why cartridge razors so often cause irritation.
Users who heed this advice often experience more irritation for the reasons mentioned above and then they seek an even milder razor. My advice to you would be to use something more efficient. It's counterintuitive, but if you can accomplish in one or two passes with an efficient razor what would take 3+ passes with a mild one, then you are saving your skin some trauma. I can't begin to tell you how many customers we've had with sensitive skin who have realized that efficiency is the best relief for irritation.
