In my opinion everybody is ¨normal¨. I mean what even is normal, what makes you normal, Your personality? Your Friends? your preferences. Your gender and sexuality has nothing to do with being normal. Its just how you feel. Nobody is normal, everybody is DIFFERENT. No offense.
And whats wrong with liking your own gender. Just get used to not everybody has to like the opposite gender. Its like having to do one thing your entire life, not everybody has to be straight.
