He Br,
Your questions and opinions are so basic to the "straight boy" genre of
Broke Straight Boys and the whole "Gay for Pay" subculture online. Among many of us in here we have debated these very questions for years. How straight are they really? How can a truly straight guy ever perform
well sexually with another dude on camera and still be 100% straight? At what point is it accurate to label them bi or outright gay? Can we ever be 100% accurate? Fortunately there will never be a definitive answer because it's all so subjective to the outside observer. So nobody's opinions on this will ever be categorically proven to be wrong. haha Sexuality is so complex and varies so much from person to person that it's impossible to get into someone's mind and understand all of their sexual motivations and kinks.
Even if all of us were Ph.D's in psychology, sociology and anthropology...I dare say we could never conclusively "prove" the answer to any of these questions. Fortunately for our own intellectual stimulation (and sometimes entertainment) we will never cease to wonder silently or aloud, and even offer our own opinions on the subject. Especially so when we are faced with these very questions on an ongoing individual case by case basis. haha Having said that, we can kind of prove when somebody has outright lied to us about not being gay and then we find out they
are, and actually self-identify as such elsewhere. But when it's not that conclusive and falls into that grey area of the straight/bi/"curious" spectrum...it's everyone's best guess. lol
