When you
were in your teens, Simple ? You are nine
teen, if we are to believe your profile. You are still a teenager. Your brain is still forming connections and you're probably not completely grown up yet. Give your brain and heart time to evolve and make more definite choices. I'm not sure you have to define yourself right now, but now is probably a time to take in some experience and to try and see where that leads you.
There will be a moment when your truth trranspires, whether you tell people or not, at some point someone will start questioning your social life and who you are attracted to. So you could be the "asexual" guy, the one who's not interested in having a relationship, the one who is dedicated to the community in order to fill a big void -- that is if you feel that void -- you could be the artist, the one that everyone admires secretly but feels sorry for because he's "so tormented and instable"... but most of all you could just be Mr Ordinary (with a different type of sexual drive). The thing is you have to see how things pan out for you socially and also legally. What are you and what are you not allowed to do in Kerala? This might colour how you play out the rest of your life.
As for your parents, if they are true Christians, let's hope they understand the idea of Love being of the utmost importance in the expression of their faith. Being Christian doesn't mean judging others for choices they haven't made. Your job is to convince them at some point that it's nothing they did, nothing you did, but maybe something God did... or planned (that is if you believe in God) -- some people say that God doesn't make mistakes, and they might well be right.
