Hi and welcome. Using a shaving technique for leg hair is quite simple. Just soak with warm water, by some shave cream with aloe and shave away. you can also by some hair dissolving products like Nair. I do believe youll regret it in the long run as will be itchy the day after and may cause discomfort at night when your trying to sleep when your legs rub up against eachother. Also your legs may sweat more with no hair and also you run the risk of it getting thicker down the road.
First get them wet and use shaving cream. That way you dont get a dry shave. That is when it burns after you shave. Then just shave up your legs and KEEP IT WET!!
