<human>: So, I'm 26 years old and have a girlfriend of almost 6 years. We just got engaged about a year ago. Everything is great except for one problem. I have a much bigger sex drive than her and its starting to get frustrating.

For about a year now, we have only had sex once a week and I feel like I have to work it out of her. She turns me down constantly. I'm so incredibly attracted to her, so this cuts me to the core. I always try to be a good boyfriend and very easy going. I send her flowers or candy to her work for no reason except to show her I'm thinking about her and I love her. I am always trying to do something fun and spontaneous to keep our relationship fresh. I always make sure I am well groomed, smelling good and look good for her. But within the last year I find my self very frustrated with our sex lives.

The last thing I want to is make her feel like an object, so I just let it go. But with us getting married soon, I am starting to worry more about it. I just think as a 26 year old I should be having more sex than once per week. But most of all is the fact that she knows I'm horny and acts like there's nothing she can do about it. She doesn't care if I want sex, if shes not in the mood, it's not happening. But if it's been longer than a week I feel like she just does it to get me off her back. I know she enjoys the sex when we have it. I ALWAYS make sure she gets hers. 

I am really easy going and don't ask for much. I'm worried that we aren't sexually compatible and it also worries me that she doesn't really care about my sexual needs. Sex is on her time only.  

Am I asking too much or is she being unfair?

Can you condense the text into a few key points?
<bot>: Seemingly good relationship except we only have sex when my fiance' wants it and she doesn't care if I'm sexually frustrated.
