I think I disagree with you, cyp6. You should probably not lower your standards because doing that would only get you into an unhappy relationship. If you can only stay attracted to super-hot HB10s, then there's no point in getting involved with an HB9 because you'll just end up cheating on her.
Now, if you really think you yourself are not that high-quality, you should improve yourself to bring yourself up to your standards.
If you think your standards are just unrealistic, you might reconsider them and decide if you could satisfactorily settle for less. But don't just drop your standards because of other people's opinions.
