<human>: Can you give me the gist of the text in a nutshell?

I'm a guy, 21, and she's 20.

I've been dating this girl for eight months now. We've had insane sex in every single imaginable position, style or way during those eight months, up to ten times a day.

I really like this girl. We had an argument a little while ago, and almost broke up, which left me pretty far from indifferent. I don't want to end this relationship, *but...*

The sex has become painfully boring to me. I used to enjoy it quite a lot, I very much looked forward to it, but now, it's become a routine I don't particularly enjoy. I find myself rather playing video games than having sex, which is very, very weird to me, as I'm the type of guy that would travel 50 miles for fifteen minutes of hoo-hah anytime. This is my first long relationship, and I'm unsure whether something like this is even normal - she literally needs to be laying on top of me, naked, for me to even get aroused. I used to pop boners just by looking at her. 

I don't want to break up with her, but sex plays an important role in my life - hell, I'm only 21.

I've been struggling with deep depression and anxiety lately, am on anti-depressants, and although this might be the cause of my lack of interest - but I honestly think that I've just overdid it with this girl, and killed the spark by turning my wildest perversions into something so everyday and common.

So, a question for you, r/relationships, what should I do to bring that old spice back? Any ideas, tips, suggestions? I don't want to pursue another relationship, nor do I want to risk this girl by cheating on her (although that would definitely solve the sex issue).
<bot>: My girlfriend doesn't attract me sexually anymore, but I really, really like being with her. What can I do to bring the old spice back?
