Not all people who watch massive amount of pornography become transgenders. There are also a lot of people in frustrated countries like Iraq, Syria, Egypt, India, Pakistan and Bangladesh who haven't had sex in their lives so they watch a lot of porn. This doesn't mean that they are going to be transgenders. If you google which country watches more porn, I am sure Pakistan will come on top. I don't know why but people must be really frustrated there.
Haven't have sex all their life!

I can't imagine myself without sex for a month.
I have seen the movie "the kite runner" and just like in the movie some of the people in those countries rape men and kids but I don't think they become transgender. Tranny are trannys since the start.
