I've noticed some dialogue lines that don't quite make sense, like "Are you saying my dancing made you hard?" Uhh, no Stephanie, look a bit closer, I'm not hard at all, come on.
From a storytelling standpoint, exposing yourself in the middle of a party will likely elicit a different reaction depending whether or not you're sporting a raging boner. I'm not too proud to admit that I know this from real world experience.

So aaanyway is there a value that can be called to determine arousal percentage or something like that? For example NPC could trigger different dialogue based on erection at 0%, 50%, 100%. You get the idea I'm sure. If this is not yet implemented, I really think it would be worth doing for storytelling purposes.
Let me know if you have any ideas!
