I don't worry about it - can't see any benefit. It's been a long time since I've seen a girl and though "I'm not good looking enough". That's a bad place to be.

One thing I would mention ; looks, even within the perimeters of unchanging physical appearance, are fluid.

Two identical twins walk into a bar, exactly alike down to the side their cocks are hanging.

One, mumbles, won't make eye contact, doesn't take the lead in conversation, fidgets etc.

The other is confident, creates report etc.

Ask a group of girls to rate them on physical appearance alone and their will be a large variation in favor of the confident twin.

(this obviously assumes the girls are unaware of the experiment)
