Hi,
You ask a very interesting question.
As the game was being developed, we had a team of testers who provided beta testing and general review of the game. One of the issues that came up is that many of the testers and other users prefered to have the game limited to what is generally considered "foreplay", and leave the actual intercourse activities to ths couple to complete on their own. After polling our early customers, that was the overwhelming preferences of the customers. So the actions in the basic game do not include intercourse. What we generally hear is that "we played for about 40 minutes, then lost interest in the game and went for it"
However, we recognize that other couples would prefer to have the game go "all the way". Thus we decided to let add-on packs provide that for those who want the game to go there. There is currently one add-on pack available, which includes a large number of intercourse and other more intense actions than those in the basic game.
There are also other add-on packs under development. Beside action packs, the action editor makes it possible to add any sort of action you want to the game. In fact, the add-on packs are written using the action-editor.
So to answer you question, the basic game does not include intercourse at all currently, there is no "lock-out" in the demo version, that is just the way it is.
Your question has intrigued me enough that I am adding a Poll to the forum on this topic.
Thanks,
