I, personally, like adult stuff. If it fits and does not look forced. If you do something like that, be sure that the animations fit, otherwise, leave it. Clipping and erratical movements etc. in such scenes is a no-no. Better to skip then. Get some help from FOW ;P
BUT: The game has other issues atm so i really don't get why this is something to look into. First thing would be to get a more fluid gameplay and get rid of bugs like stuck conversations or npcs you cannot take into your group anymore or even talk to.
First the basics then the polish.
I like the way this is going but PLEASE do not overdo it. It's a slim line.
