@kescher idk, imo that's already co-covered in specific. I like enthusiastic because it highlights that even when no external pressure is applied, sex is something you have to want.

I.e. a person in their first relationship might believe sex is just part of a relationship and believe they want it the normal amount, without any pressure from their partner, and not realise that "eh, guess we'll have sex" isn't really wanting it. E for Enthusiastic highlights that if you're not enthusiastic about wanting it, something's amiss; I find that very helpful.

So E for Enthusiastic & Explicit.
