Facial Shaving Question??????

Hi, I'm 18 and I've been shaving my facial hair for a while. I use the Gillette Fusion Pro Glide with Gillette shaving gel. Every time I shave I always end up having irritation. My face gets sensitive and it feels like it's stinging. It lasts for about a day. I'm shaving in the right direction and following all the standard steps. I don't understand how other men don't have irritation when they shave. Any suggestions????
