It’s easy to imagine lust might really be affection, but can affection in a first step towards love grow out of a relationship based on sex? Do you and your partner actually communicate about anything other than about sex? Do you have anything in common to build a relationship on if sex wasn’t the main component? Would you actually be okay with being seen in public with your sexual partner or do you just see them as a guilty pleasure to be hidden away but never associated with publicly to those that are within your inner circle? Is your reasoning for not making your casual sex partner a mutually decided one of just fun and sex only, are you ashamed of association with him/her because their not your “dating type”, or are you ashamed to admit how you began your association with each other? If there is shame, there can’t be true affection. At the end of the day, the questions that need to be answered are: does this person add to my life? or does this person just scratch an itch?
