<human>: Can you provide a brief overview of the text?

My lovely lady and I have been together for 4.5 years. I love her very much and we have a good relationship except when it comes to sex. She was a virgin when we met and we had sex ~3-6 times a week for the first 4-ish months of our relationship.

After that it started to taper off slowly. To the point where it would be maybe once every 2-3 weeks. I've talked to her multiple times about how I'd like to have sex more but it always boils down to her being too tired, not feeling pretty, not clean, not in the mood, etc.
She does have difficulty reaching orgasm without a bullet but I never fail to get here there whenever we have it on hand.

Lately I haven't been suggesting or instigating sex and waiting for her to do it. Generally she just teases me or riles me up then says she's not in the mood. It's frustrating.

Although I would like to have sex 1-2 times a day I'm completely reasonable when it comes to a realistic amount. If we had sex twice a week I would be fine with that for the rest of my life, I have no problem servicing myself. I just don't know what to do, she is *never* in the mood. Help?
<bot>: 4.5 year awesome relationship, I have high sex-drive while hers is almost non-existent. How can we make this work to fulfill both of our needs?
