Seeking Games that allow players to adjust the size of the (main) character's body parts at the start of the game.

Just like the tittle said :3
Some similar games I played: Magic Shop 2; Degree of Lewdity

I think Corruption of Champions, Corruption of Champions 2 and Trials in tainted Space will scratch that itch nicely.

TiTS is probably the best of them, although I have a soft spot for CoC.

I don't know the rules about posting off-site links so I won't, but search for "Fenexo" and click on the "play" tab. If you want to try CoC, I recommend getting the mod by kitteh6660 as they continued development after the game was abandoned.
