Sounds like Tim, The Teenage MC by Rass Senip
I originally found it elsewhere long before I found this site so it may not have been here that you read it, but at least you can get it here.

I just saw the author has re-written a lot of the story and even has new content that has been split into multiple stories. This is the new universe:

Chronicles of Tim Brandton — A Universe from the Mind of Rass Senip
The epic tale of Timothy Jasper Brandton and his struggle to grow up and live a sane life despite the corrupting influences of his telepathic and other abilities. This is a story about love, friendship, and following one's heart while facing the temptations of power and control. Crossing 9 nine books and over 3 million words, it touches every form of sex. While mind control, incest, and other tags are included, they are not the focus of the story. Chronicles is written from the heart. While it contains practically all forms of sex and fetishes (usually in a single scene and then never repeated) and has MC content, it's more about the characters than the sex. They want to have fun yet do what's right. This is not the typical MC story. In some ways, it's an anti-MC story. "The Chronicles of Tim Brandton" is overall heterosexual, but there are a few bisexual (mfm) and even fewer gay and lesbian scenes (if a guy in a woman's body having sex with another woman can be considered lesbian). If that content bothers you, you can just skip over them.
