I've only ever said it would be nice, I can clearly see how much work it is to make any new character. I don't know how to code this specifically or make consistent animation otherwise I'd try modding myself. I don't even know what's possible, so that makes it hard for me to suggest things. And I'm already so impressed with what's done.
I only came across one bug where an enemy attacked and I failed to react in time, and then a different enemy attacked and I reacted in time but the previous enemy was still in the process of the sex scene and it made a cooy of the character while that was happening and I was still moving around attacking. If I had to guess I just got attacked again in the very short span of time between the 1 second to use special and the beginning of the sex scene.
