Forced Bisexual

A man, or in this case, a "man" is defined by and large by his sexual preference. His life is dominated by what his dick is attracted to. For example, a cowardly submissive is sporting a boner, however secretly, for the sadistic cruelty of a femdom. Being a submissive with only Her intentions in mind, he could easily be led down this path, to his great disdain. When the Mistress commands a performance that defies a man's sexual identity, she can really wreck havoc on his mind. This is the part I love the most. Going against your own carnal pleasure, transcending your inhibitions for the sake of your Mistress, is without a doubt, very arousing. Not just for Mistress, but for submissive too. If it holds true that a sub's sexual arousal is triggered by his Mistress's satisfaction, then it would only seem logical that while giving head to a big black cock, he is as aroused as he would be if he were with a woman.

Imagine living your life as a straight male. You may not get laid very often, but you know that when you see a girl with tight pants on or nice firm tits you will more or less get a boner. Now suddenly everything is turned upside down because now you are inexplicably turned on by men as well, if not from your own interest, then from the keen and cunning coercion of the woman you serve. It is one of the ultimate forms of submission.
