A person who expresses love through physical affection is said to be in this love language.
Other than sex, those who identify physical touch as their primary love language express their feelings of affection by having their partner hold their hand, rub their arm, or give them a massage at the end of the day, for example.
Having a glass of wine and watching a good movie on the couch with your significant other might be your idea of the perfect date. The only thing you want is to be physically close to your partner.
