It is true that people need some affection that is physical, for human beings are mind and body. Our soul seeks the correct proportion of pleasure that is sensed-physically and that which is the mind's pleasure.
However when analysing pleasure the future must always be taken into account. It is silly for the libertine to get carried away into the abyss of bodily pleasures! Yeah sure the hug feels great during that moment! But is that going to contribute to the future happiness of the people being hugged?
Many people in the world need more than a hug they need a chance to survive! They need to have enough of a Caloric intake to live! The UN Food Program didn't have enough food to help poor people because of stupid economic politices; now Uganda has an increase of people that are starving. Yes hug people, it helps make people happy but don't make it your life! You can do a lot better by organizing a political revolution! Hug someone after you've done something to deal with world hunger!
