There aren't a lot honestly, the one you see in this scene in specific is the most interesting one. There's also another early enemy who attacks by blowing kisses (but they strip after taking 50% damage and stop), and an event in the second(i think) town where you can end up getting a thighjob/kiss combo from a cow-girl. But that's all the kissing in this game.
It's also honestly pretty short, and i don't think it's worth it if you don't understand japanese or know how to machine-translate your game.
