Wow, you guys are still debating about this. Here; stop being an ignorant pony and go read some actually stories about transgenders. Sum1sGuru, I suppose you haven't read a single of my previous points in my previous posts.
Trickery? Really I'm sick of this... Honestly what makes you move, think, play games, solve problems, learn new things, breath ect.
Your Brain.
If your brain didn't release seratonin/dopamine to get you aroused the last time you saw a female naked, but it did for all the sweaty jocks, how would you feel?(There is more to this point, just take everything that makes you a man, imagine that all gone, then think of you enjoying everything that makes a female a female. Now incorporate social factors/influence, family factors and influence, predetermined genetic roles, so forth. Everything tries to make you a man, but it never feels good) Like your living in a prison, leading a fake life.
Sum1sGuru just stop being so closed minded, ignorant and so positive you're right. Try thinking you might be wrong and consider the alternate ideas. Then you will see, you are so smurfing wrong.
