<human>: Can you condense the text into three sentences or less?

My girlfriend Sarah and I have been in a relationship for one year, six months of which was long distance with ~monthly visits. Initially, we would often have sex 4-7 times a week. Obviously, over time, frequency typically goes down in most relationships. However, Sarah and I are both frustrated by her lack of desire for sex - we probably average once a week now. 

I often feel guilty for initiating, and rejected when it doesn't happen. Truth be told, I would be happy to go everyday. This is unusual for her as well, and not just a feature of the relationship getting stale. 

Sarah has been feeling pretty down for the past few months, which has probably got a lot to do with this. We are both pretty kinky, but it has been hard to enjoy that given the lack of frequency. 

Sarah and I love each other, and rarely have disputes (I will spare you a list of her great attributes). We want to stay together and have more sex! She is planning on seeing a psychologist a.s.a.p.

Could anyone offer advice on how to deal with this? We talk about it openly, which is a good start. Any advice would be appreciated!
<bot>: GF isn't horny anymore - both frustrated by it and looking for a way to improve her sex drive. Cheers!
