I have to say, I experienced the exact same things right after I came out and continue to experience them still. Let me give you the specifics; Libido - considerable drop compared to what it was pre-T-day, and like you, stories really get me going now and videos almost do nothing for me. Porn is weird and kind of boring to me now. I still look at it from time to time and enjoy it momentarily, but what really gets me now is fantasy; I'm talking like in my head, eyes closed, wind blowing gently through the open windows. It's no longer about just getting to the end, its now about the journey to get to that end and enjoying every step of it. Oh and toys that can go places are now my preferred method; the old way feels foreign and wrong on some level. I do still get the unwanted pops from time to time, but the frequency has gone waaaaay down and it is much more manageable now.
Its really interesting that you talk about how people started treating you differently; that was one of the very first things I noticed and it was kind of surprising, but not unwelcome. Like you, I have really only begun to transition; I am not on hormones yet or even presenting publicly, but its almost like people can sense the change and they treat me much more softly now than before. It is such a welcome change because I feel like people are finally starting to treat me the way I always wished they would.
Its really nice to see that other people have experienced some of the same things I am experiencing, it helps remind me that I am indeed sane.
What a long strange trip we're on....
