I'm not the best sex he's had. How do I deal with that?

Chelsea
My boyfriend is overly honest sometimes and after I told him he was the best sex I'd had I told him I wanted to be the best sex he's had. Well after a drunk night of him and me telling various sex stories of us with others, he told me this "best sex" scenario and it sounded magical. It was with some girl he loved and who loved him on a balcony overlooking some city. Magical as hell. But I feel like I'm not good enough. Like I can never outdo magical sex like that. We love each other, and he thinks all is well in the world, but this shit weighs on me day after day. How do I cope with not being his best partner?
