I'm really surprised by and amazed at the level of vitriol in this thread. Admittedly, the original question was not typical or even appropriate for this forum; it is completely off topic. However, there is the potential for certain NBE herbs to cause impotence. The question is whether or not a dose high enough to cause impotence is also high enough to cause breast growth which he does not desire. I would guess breast growth would come before impotence, and such high doses could be toxic.

Is he seeking attention? Perhaps, and by shoveling abuse at him, you're giving him exactly what he seeks. Being an apparent submissive, and possibly a masochist, such abuse is like manna from heaven for him.

It does seem odd to me that his mistress wouldn't know how to make him impotent. Based on my experiences with people in the BDSM lifestyle, they usually seek each other out, share information, belong to local groups of like-minded individuals, etc. This is how they learn to do things more safely and minimize risk. There is risk in everything they do, but it can be minimized. Still, mistakes happen and people do get hurt.

I would ask if he really wants to become impotent or if this is strictly the desire of his mistress. As a submissive, he still has the right to say, "No." Whatever contract they have can be renegotiated at any time. As his Domme, his mistress also has a duty to look out for his overall well-being. If causing impotence through chemical means could cause permanent harm to him, that's something that both of them need to examine and decide whether or not to pursue. There's a difference between impotence and training him not to respond to erotic stimuli so that he controls his erections.
