Oops yeah those are all bugs. You should be able to interact with Finn and the baby as well... Will fix soon!
(The Moocha scene showed up out of nowhere because I stupidly forgot to add a certain condition in previous beta lol)
"When deciding to participate in foreplay mode, once you finish and click the heart the game will state there is an error and take you to the beginning to where it asks you again if you wish to participate in foreplay mode." => Do you have screenshot of the error?
