Are short guys insecure?

I know a good looking guy but he's quite short like around 5.4 bordering 5.5. Moat of his female friends are taller than him. The girls he has dated are usually shorter than him. However, he keeps calling everyone shorter than him as "short".

He's also exclusively friends with women and does not seem like he has male friends.

Is this OK to say so? Is this a sign of insecurity?
