I am certain that everybody is bi to some degree, but most ignore, or hide, their gay side desires, as they are not so important. Anybody who says they are 100% straight is just denying their feelings, and are probably homophobic.馃檪
I'm not certain about bi but I do feel most if not all are curious sometime in their lives and if the right chance comes along maybe they would try . And you may be right about some being drilled by parents or peer pressure into blocking their feeling and afraid to let it go .
I think you are projecting. I am 100% straight and don't think I am homophobic at all, I don't mind when 2 guys make out in public I don't mind seeing 2 guys walking hand in hand or getting married. I do find the idea of me doing anything with a guy repulsive does that mean I'm homophobic not at all, maybe androphobic at best.
@kayoshin I think that your problem may be early conditioning by adults, everyone has the ability to, at least, enjoy just a hug from another male, and like the feel of their body close to you.
Hugs are not necessarily sexual. Do you think about sex or get arroused when you hug your mother? I never said I don't hug or shake hands with my friends, it's just free of a sexual connotation it's guys being guys not guys being bi.
