The date and sex options aren't available. I'm not sure if this is actually a bug or I haven't played the game correctly. I can put characters in the bed, but I can actually select any options to date or sex. It does say something like sexual requirements not met yet, but I can't even date. Does anyone else have this problem/know a solution.

Have you unlocked those options for the characters you're trying to date? 

 (Click the character, go to Character Info, then Training and Rules (the heart/drumstick button).  A panel will open up with various training options that you can purchase using the character's Loyalty; one of the basic ones is Dating.  Sex-related trainings are on a separate page.)

Are you in your mansion? Otherwise you cannot take those options.

I haven't checked the training and rules yet, thats probably why. Let me check...
