<human>: Condense the text into a few key points

We've been together 9 months. I have a higher libido in general than he does. It's difficult to be turned down and not feel rejected, but I try not to let it get to me since I know it's not personal. But that's easier said than done.

This weekend, I initiated some physical intimacy. He didn't seem incredibly into it, but played along and seemed to get more interested as things progressed. Then it came to a screeching halt before either of us were finished. He just completely backed off and stopped without explanation. 

After a long, awkward silence, he apologized and basically told me that what I was doing just wasn't doing it for him. Admittedly, I was pretty drunk and definitely not at my peak performance. But even still, I feel monumentally embarrassed. I moved from feeling that despite his lower libido, he seems to enjoy stuff when it's happening to feeling like he not only doesn't have desire for it, but also doesn't even enjoy it when it occurs. 

The embarrassment remains and my confidence is totally, completely shot.  Nothing has happened since. I'm terrified to initiate anything because I'm afraid of a repeat rejection. He's not known for initiating things, though, so I feel like if I stop initiating, we might reach /r/deadbedrooms territory, which I also don't want. How can I get my confidence back without risking further damage to my severely bruised ego?
<bot>: My low-libido boyfriend cut intimacy short because I was drunkenly performing poorly and now I'm embarrassed and afraid to try again because my confidence is shot. What should I do?
