Me [23 F] with guy I'm dating [24 M] compared me to another girl in bed

I have been dating a guy for about 6 weeks. We were having sex this weekend when he said "the best hookup of my life was when a girl did X, you should do X." It made me feel like I was being compared to another girl, and it made me feel like I wasn't living up to this other girl in bed. Should I tell him that it upset me? Or is this something that I am blowing out of proportion?

tl;dr: Guy I am dating compared me to another girl in bed, not sure if I should say something.
