Can you shave your legs with just water?

Of course as long as your carefull...Im 17 and when I started shaving I used shaving cream but I really didnt like it so I thought I would try with just water...and ever since then I haven't used shaving cream in two years...I can rn over my legs or armpits real fast with a razor and water and nothing at all happens to me but as soon as I use shaving cream and take my time my body is covered in Knicks and blood
