Lets ask a hypothetical question. Say a person was to get into a relationship with a "lad about town" eg. someone who was use to a busy sex life with a long string of sexual conquests behind him. Is it unreasonable to expect that person to be monogamous? Would the lure of new conquests-strange-new flesh be too much for him? Would he ever be totally trust worthy? Would it even be worth while even getting into a relationship with this person in the first place?
