I think sometimes having a foot in the door helps anyways. Of course grossly misrepresenting yourself is a bad idea but enhancing a bit, why not? Also, it is indeed possible that your potential partners may value other aspects besides your appearance, not everyone is obsessed with looks. But of course your mileage may vary depending who you met in your life, and also based on where you live / local customs etc.

Then there is the issue of how you perceive yourself, when I was in my 20s and 30s I used to think of myself as not attractive, but now when I look back at my old photos from a more detached point of view, I think I was a fairly attractive young man. Excessive self criticism can be bad and artificially put you down.

After entering a "serious" relationship and then getting married in my 30s I was able to look at myself in a more balanced way. I think my previous self-criticism was fuelled by some vague fear that I would never find a partner and I would live a lonely life. Probably it's a common thought among people of that age.
