I just find the subject to be ridiculous. If you enjoy any form of sexual interaction with both sexes then you are simply bisexual. Why is that so hard for so many to admit to themselves? I completely reject this foolishness of "the straight guy getting head from a gay guy". Ridiculous. If it challenges your masculine identity then stop having sex with men. If it's something you're embarrassed about then stop having sex with men. If it's something you feel guilt about the next day (or hour even) then stop having sex with men. Once you stop having sex with men, and have sex only with women, then you can call yourself a true blue, red-blooded, breeder boy. But until then, deal with it, and call a spade a spade. You're bi.
