One last comment from me on this.
It could be a relieve for you to let the idea of the preg theme go completely.
Many would breathe a sigh of relief if this potentially controversial area would be respectfully ignored (ie.: not implemented).
Guess the majority of players that voted for the "Improved Sex & pregnancy" update wanted the sexual sensations but not the preg anyway!
Yes some players would whine that they want impregnation, but that is rly the only downside of not implementing "it".
(PS.: There are ofc other themes in second helpings that i'm not particular into but totally understand that they are wanted by many other players and make sense in regards of the games focus.)
