Sexy Dreams v3.7.2 was released this week and contains an updated database, I went through all the desires, and removed all duplicates and updated all the levels to be more consistent. The new guidelines now apply to levels.

Level 1 - Basic interactions like kissing and drinking, not much touching involved at this level.

Level 2 - Lots of touching and kissing, some flashing of skin etc.

Level 3 - Lots of sexual interactions, but no intercourse or penetration at this level.

Level 4 - Only desires which result in intercourse and orgasm are at this level.
