The new mechanics are good, but I agree with the comment about the play area sort of dragging down the sex method. On the new mechanics themselves I think they'll be great long-term with certain characters (assuming there's more) having different likes and dislikes.
Dick customization, not just for looks, but changing the stats they do, might be an interesting idea. (btw I enjoy the fact that it's much more human-looking/species ambiguous right now compared to Monster Layer)
No one's really mentioned it, but the secondary animations and dialogue are great too. People sometimes struggle with sex talk in games but it works perfectly so far with the default character.
