Etheria's Romance Overhaul 3.8  

ERO: Etheria's Romance Overhaul 3.8: One-Sided Crushing, Blushing, & Gender-Specific Turn-Ons and -Offs!

VERSION 3.8 IS OUT! This mod requires S4CL version 1.75 or later, if you don't already have it then please follow the short instructions under the "Requirements" section below.

Automate your Sim's physical traits from CAS, see how attractive, how compatible, and how friendly your Sim views all other Sims, randomize everyone's turn-ons and -offs, enable attractiveness buffs on your Sims, and much, much more! You'll have to try it to get a feel for everything that it can do! There are even more options available in the shift+click menu on each Sim for an experience tailored exactly to your liking!

ERO 3.8 features:
-Added the Tiny Bulge, Tiny Butt, and Tiny Chest traits.
-Made the menu display and close a bit cleaner.
-Toned down the Flirty buffs' weight on a Sim's mood, though you can always disable these buffs entirely by going to Global Settings and turning them off if you don't want them to affect a Sim at all.

Note:
Some of the Sims 4's tags are wildly inaccurate. For one particularly bad example, the game labels both red and purple eyes as "amber" eyes (I don't even). There's more detail in the two CAS screenshots included in the pictures section above, but right now the only fix is to set these strangely-tagged ones manually (the full list of hair and eye colors and EA's versus my tags is in those screenies).

Description:
The Sims is a game we know and love for its ability to engross us in making lives of our own full choosing and control, but let's face it: for many of us, it doesn't really feel real in certain aspects of the vanilla game. One of the biggest of these for me is the romance, or rather, the lack thereof! When Sims touch and kiss, they barely get closer to each other for more than a second! C'mon, who the heck hugs their partner like that?! Things like this mean it often feels like the game treats romance as a side-gimmick rather than a real and fully-fleshed-out part of life, and I find myself feeling dissatisfied with how the Sims I have who are supposed to be completely head-over-heels for each other are just...coexisting lukewarmly. I aim to be part of what changes that, with a mixture of attractions, affinities/compatibilities, and opinions your Sim has to/about other Sims, among many other features!

So I felt like creating a mod that makes romance a thing in the Sims that people can connect with, one that's best made possible through a unique union of code, animation, and storytelling!

An attractiveness system based on both looks and personality, but also life experience! 

Ever wanted to feel more attracted to the Sim of your dreams? What if a guy has gray hair and that's just not your thing? What if she's short (you didn't forget about height slider mods, did you?) and that's totally your thing (cute teddy-sized girls, amirite?!)? What if the Sim has kids and even though you're looking for a serious relationship, you're just not ready for possibly becoming a step-mom? Sorry Simdr date, you're great but that?s just too much for my Sim to handle at this point in their life!

Or if she's an airhead who spends half of her day talking on her phone and only ever wants to talk about her friends and makeup? Boorring.

That sweet introverted girl who is quiet to most, but opens up like a blooming flower when you start talking about video games? Totally your style.

The guy who takes a ridiculous amount of pride in his hair and his swag? Ooh, a bad boy's the one for you, eh? Your Sim has a high Affinity for that! Or at least for now they do!

Has your Sim dated 20 different Sims and their secret admirer is a complete relationship newbie? Well, maybe that admirer won't feel so warm towards you after finding that little piece of info out through the grapevine!

Want to know if a Sim has had their first kiss? Ask them! Want to know who that person was? You can ask them that too, but careful, they may not want to answer if they don't know you well enough or think you're a jealous and destructive person!

Or what if a girl's a homewrecker basically as a hobby, specifically seeking out men who are already taken and trying to Woohoo their brains out like it's some sort of winner-takes-all game? ...That would be kinda hot to some Sims, huh?

Maybe your Sim wants to try out that classic temptation vs. foundation in their love life only to regret it horribly later as they're forced by their spouse to tell their kids about their affair? Ddrrraama!
These are all examples of the kinds of scenarios you can insert into your game with ERO! You decide, with an attractiveness system that makes BOTH physique AND personality come into play!
(Seeing attractive features and personalities will make your Sim feel flirty. If your Sim sees someone who has a certain number of traits they find attractive, they will get whims to want to flirt with them!)
