How much does quality of sex differ by girl?

Serious question. My notch count is 10. A couple were straight up bad. A couple were a bit extra good. I'd say the difference is most noticeable with oral. But frankly, they're all pretty much the same.

If the woman is really, really attractive (i.e. Taylor Swift), it probably wouldn't make a difference. Because what makes a difference is things like size (not too big), and enthusiasm. Your friends might be more impressed but that's it, with regard to quality of sex.

Am I missing something or is this what others have experienced too?
