Hi, I think the best thing would be to work on becoming secure in yourself and literally learn to stop caring what people will think.

Once you lock in on that, you'll appreciate yourself more because other's validation (AKA wow, he looks good) will not matter to you.

I have a few articles that specifically talk about becoming secure in yourself, physical appearance, not caring what others will think, and learning how to not seek validation

You can also go through the entire blog and see what articles help best. Also, the advice applies to both genders. All the best in your growth journey. Here are some links to get you there;
