Sorry to hear! There might be more variations later, but it's not a priority at the moment!
I like the idea of more cock options, especially since all of the "human" options look circumcised. Uncircumcised would be a nice addition. I've created several "sissy" characters, so a tiny cock option would help, as all of the human ones are just thicker/thinner rather than shorter/longer. On that note, Chastity cages would be a fun addition to the game.
