How do I shave my legs?

Hey guys. So I've been wanting to shave my legs for a while now, but I really don't know how to do it. I know there are a few ways of doing it but I don't know which one is better (or how does it work). I'd prefer a long-lasting solution since I'm pretty tall and having to shave every day or two sound really annoying, but whatever is better.PS: I've seen a couple of posts where people respond "Don't shave, hairy legs are the best!" and stuff like that. Please don't. It's fine if you like them, but I want to create an opinion for myself, and so I want to try and have my legs shaved for a while.PPS: I'm not a native english speaker, so sorry for the possible heart attacks me and my grammar might have caused you.
