There is a fine line between SEX and LUST.
When you are in a relationship, SEX is a really important part, it helps you know how you feel about each other, sexually and how much you enjoy and are comfortable with each other.
But LUST is when you came into a relationship only for a SEXual relationship, which can be really a turnoff or annoying. People don’t get that without feeling you may get laid but it becomes a headache or annoying for the one who wanted to do it after some time or with the person she was really in love with.
Because SEX is really a romantic gesture which should be done rightly and correctly. Great SEX shows how well you know the other person and you know how to give them pleasure, which most people don’t get. It’s good to know what you want and desire.
