1,2,3, and 5 for me. I wouldn't really say I'm an addict, but I think of Tgirl pics and movies as a hobby- a hobby I can't share with many people without them thinking badly of me. It's very nice to have a place to come where you aren't seen as perverted. A friend of mine says that "people can't help what turns them on"... I'm not sure many people really believe that- even the folks who say they believe it.
Everybody needs a place they can be themselves...
