My face, especially the neck tends to get very irritated when I shave regardless of the method (electric or blade) used. After a visit to my doctor and another to a dermatologist, the following is the method that works best for me:
I use a multi-bladed razor (Fusion, Mach 3 etc) in the shower after soaking my face in the hot water spray for a few minutes. I'll clean the rest of the body and hair first so the hot steam and water has a chance to soften the hair on my face. Using a shaving cream for sensitive skin (Nivea at the moment), massage it into the face don't just pat it on. You want the lubricants and ingredients to do their job of lifting the hair and softening it. Now the hard part, develop a pathway for the blade that you will stick to from now on. Meaning, shave in the same direction every time you shave. Against the hair grain is best and you won't get a very close shave for a week or so until your hair learns to do what you want. Don't pass over the same spot more than twice and don't press down on the blade, you want to skate the surface and let that razor sharp piece of metal do it's job.
Once I get out of the shower, dry off and whatnot I'll splash cold water on my face to close the pores. Afterwards, moisturize! Aftershave balm, your wife's chi-chi natural moisturizing goo, whatever...
When I really don't have to look decent, I'll forego shaving altogether for as long as I can. If it's a busy week, late morning or nothing that involves pretty ladies licking my cheeks I'll use a decent electric razor during the week and only use the blade for the weekend. I'll use 'Lectric Shave' pre-shave stuff before the electric razor and the same aftershaving ritual as above.
It might hurt to think it but if you've got a sensitive face you have to start thinking like a 'girl' when it comes to taking care of it. Moisturizing, cleansing and spending the extra bucks for the good stuff to keep it looking nice. I like natural products from places like Lush and Body Shop that don't have chemicals or alcohols in them if I can find something that works. At first it'll cost ya to find something that works for your skin type and needs but it's worth it not looking like you have the pox.
