Don't have a father to teach you?
http://www.gillette.com/en/us/mens-style/how-to-shave.aspxAs far as I'm concerned, the Gillette Sensor Excel is the best razor ever made. It does a good job and the blades are (relatively) cheap. Some of the new models may work nice but when the blades cost $5 or $7 or even more each then it just gets ridiculous. Luckily I don't have to shave every day and I usually keep a short goatee so one blade will last me a month or two. I bought two 24packs of blades on sale at Sam's several years back for $8 each (at a cost of about 34 cents a blade). I'm down to my last two blades though
luckily its blades still seem to be plentiful and available although they typically run about $1 to $1.50 per blade at places like Walgreens.
Do *NOT* use disposable or generic brand razors. They may come in handy in a pinch but you will cut yourself up and it will take four to five times as long! If I don't cut myself with one it does a poor job of shaving and leaves me with a rash. I made the mistake of buying generic brand blades for my Sensor. I used one once and threw the other 9 blades away. They really were THAT BAD!
I personally use an anti-fogging shaving mirror in the shower to shave with and I almost NEVER use shaving cream. If I do need an extra close shave for whatever reason (or if it's just been awhile since I shaved) I'll use some hair conditioner in lieu of shaving cream. I think it works better anyway!
