Love is not physical relation. Love is the ultimate positive emotion, which encompasses care, concern, joy, praise, happiness, growth, life and abundance. We love our parents. We love our siblings. We love our relatives. We love our teachers and we love our friends. Loving a friend of opposite gender or appreciation for someone belonging to opposite gender does not essentially mean that you mean physical with him/her. Love is nothing obscene or filthy. It is a pure emotion.
