Helpers for women?

Happiness. :/

Confidence.

confidence!!

I agree with both happiness and confidence, and also I'd say having a partner who respects you and treats you well. When someone is always picking on your appearance it's hard to feel in the mood. Someone who isn't interested in your pleasure can really mess things up too.
Although, I guess being truly confident in the first place will make you walk away from people like that quickly, as you should.

more sex always makes me want to have more sex. Seems the more you have, the more you want! Also, if shes into romance, totally go with that. If the girls a romantic, no kinky shit is gonna get her in the mood, especially if shes already down on libido. Make her feel the sexiest thing alive!

For me, I know my sex drive is low when I'm overwhelmed with other crap. If I've been busting my ass taking care of kids all day, or I'm stressed because the house is a mess and I have tons to do, sex will be the last thing on my mind.

I agree with that. I don't have the ability to clear my head and "be in the moment" when I have all kinds of other thoughts and worries swirling around in my mind. I have to learn to compartmentalize so that when the time is right, I don't ruin it with a racy mind!

Confidence, especially body confidence. My fiancee is more sexual when she works out and feels good about how she looks.
