you shold ask to set one day aside and just talk to him not as a sub/slave and tell him that you can only take so much pain and that he needs to go slow with you and learn how much you can take. it sound to me like he is pushing you too fast. depending on how long the two of you have been in the relationship if this is a relationship just starting out then i would say he is pushing you too fast and should slow down a bit. and as for getting punished for asking him to take it easy on you that is so unfair. a relationship of this type is based on love and trust. a Dom/Master is suposed to love and protect there girl or boy and would never push them to take any more then what they actually can take. pushing a girl or boy needs to be done slowly so there Dom/Master can learn what they like and how much they can take:
