It was about Timmy turner at a girls camp, turned into a girl, and learning about being there. He was there because of Trixie, obviously, but the story is way better than that. Certanly not deep, but a good one. They only have one scene where he fingered himself, and a small lesbian one at the end. Great comic.

SFW preview right after the fingering scene, which is about 1/6 the way through.
