When one has the strong desire to be touched (not usually in a sexual way). Examples of touch are hugs, kisses, or just something simple as
holding hands. Humans feel this desire due to the fact the body releases the hormone oxytocin during skin-on-skin contact. Without it, adults are more susceptible to depression and infants can have developmental problems or even die. This craving can be satisfied through a friend (if you're
comfortable with affection, some platonic
relationships are more hands off) or a partner.
