Hello, and welcome.
My name is ***** ***** I will be glad to help with your question.
Your cat licks you because she's showing affection--these are cat 'kisses.' Cats groom each other as a sign of affection. She might have been separated from her mom and siblings too early and didn't have a chance to lick them and be socialized properly. In addition, she likes the taste of your skin--typically salty. If your use any lotions, creams, etc., don't let her lick you, as those substances could be toxic to her.
To get her to stop, kiss her and say 'I love you, too!' and put her down (if she and you are on the couch, for example.). You can also just leave the room or get her interested in a toy, when she starts licking. You can also wear long sleeves and long pants, and she won't want to lick you.
I hope things improve, soon!
