There appears to be a "Lovers" Bonus and some other bonus's depending on how far you are into the relationship and I would assume they do different things each "Rank up" so to say.
People late to the show, If you want to romance someone in skyrim you have to wear an amulet that shows who's interested in you.
Different amulets for different races, So if you want to woo an orc or a catman,darkelf ect, You need to wear a different amulet for each race to basically show your appeal for them? I'm still not to sure what to make of that. Skyrim marriage culture?
The amulet is basically for people who are turned off to the idea of romance and flirty things in skyrim, So dialogue will change to flirty stuff if you wear this amulet and it sorta becomes a dating simulator with some "neat" bonus's as you could say as they can serve as a pack mule and cook meals for you and maybe more things? So far that is what is confirmed, But from the "Lover" rank thing, I assume there is some fade to black cheesy moaning screen or something, Just a theory.
So if you're not into romance in skyrim, Don't wear the bootycall amulet.
If you like to rp, I say give it a try.
Personally, I think it sounds neat, I want someone to hold all my crap and make my character food:P B)
