I'm sorry if this has already been asked, but I searched through the thread and couldn't find what I was looking for. Anyway, there are all these sex skills in the game in skill trees like doggy style, missionary, face fucked, reverse cowgirl, and so on but I have absolutely no idea how to use them once bought. Do you use them in the middle of battle, or outside of battle? Do you need to be in a certain stance to use these skills? Do these skills have other skill prerequisites? I'm mostly interested in the skill where you're on top, rather than the ones where you're receptive.
