How come every time i come from extremely cold weather outside, my hands start burning inside but they are not physically warm. . i'm burning.

So the cold can cause tiny blood vessels in your hands and fingers to constrict.. Usually this can be helped by wearing gloves..

sex is when a male and female has intercourse (sexual)

tell their parents and make sure she gets from a counselor or therapist. be supportive and be there for her. be a kind and good friend. spend time with her to make her feel like she's not alone. i'm not a professional but i really hope they stays strong.
