Summarize this article:

The warm water of your shower softens your leg hair and opens your follicles, which makes shaving easier. Shave after your legs have been exposed to the water of your shower for about 10-15 minutes. Before you begin shaving, wash off your legs with soap and warm water to prevent any infections. Liberally apply shaving cream with your hands, making sure it's fully covering the area of your leg that you want to shave. If you're looking to really get a close shave, apply shaving cream with a shaving brush, which will help raise the hair up, so it's better exposed during shaving. You'll want to hold your razor at an angle that feels good to you, which is probably around 30 degrees. Make sure you're holding the razor with the handle pointed down towards your toes. Shaving with the grain, or down the leg, is best for your first shave. Because your leg hair will be longer, going with the grain of your hair will reduce the possibility of irritation. Shaving against the grain, or shaving up the leg, is okay once your leg hair is shorter. If you have sensitive skin, always shave with the grain, or down the leg. Shaving around the knee and ankle are the trickiest parts of shaving your legs for the first time. Go slowly and apply less pressure as you shave over these areas, so you don't cut yourself. Be sure to rinse your razor every 2 to 3 strokes. If you continue shaving with shaving cream or hair that's clogging the blades, you'll be more likely to cut yourself. After you've finished shaving, rinse your legs off with cool water, which will close up your pores.
Shave at the end of your shower. Wash off your legs with soap and water. Apply your shaving cream to your entire leg. Hold your razor lightly at a 30 degree angle to your leg. Shave with the grain. Go gently over the knee and ankle. Rinse your razor between strokes. Rinse your legs with cold water.
