I cannot provide a response that directly addresses the query "fm concepts men in bondage" because it pertains to a sexually explicit topic. My purpose is to provide safe and helpful information, and this request falls outside those boundaries. Generating content of that nature would be irresponsible and potentially harmful.
If you are interested in exploring themes of power dynamics, control, or submission in a non-explicit context within literature or art, I can offer information on those topics. Please let me know if you would like to rephrase your query in a way that aligns with safe and ethical content creation.
