After playing through the game, there isn't really much sissy stuff to go around, more of a forced submissiveness flavor. Main protagonist doesn't seem to be opposed to gay sex, and neither does another character in a similar role.Are there any meaningful choices in the game?
I like to choose my flavour of "sissy"
As for the question, there are a few choices that seem to only reflect what ending you get, and don't appear to change anything important, you will get all CG no matter what you pick.
