<human>: Can you give me a shortened version of the text?

Hi. I want advice on communicating this need to him. Ive always being in rough sex, but he has only gotten more gentle. 

Spanking, light choking, and hilding me down is ok. He wont do much more than that. I want him to bite me so hard I bleed and shove me onto the floor plus whips and chaining me. Honestly, my limits are electric shocking and guns. Knives are ok. 

Anyway, I finally was able to tell him and get a reason why he wont. He says I am too fragile and he is afraid of hurting me. But, I want to be hurt!!!!! 

Pleaae advise how yall got to this point in the bedroom
<bot>: My husband is a gentle lover. I need him to be a sadist to feel enjoyment. How can I make him transition?
