There's no way to coat this so I'll be straightforward. Does penis size matter?

Super insecure gay virgin here, I have some self esteem issues. And after having seen a good variety online (and I don't mean porn, well it is porn but not pro porn, some home videos I found online, also some personal experience [no one knows I'm gay and my friends are confortable being naked around me, happened on a few occasions also some music festivals]) I realized that my penis is incredibly small, I know that at least 30% is due to my overweight, working on it (doing great progress), I still know my penis is the smallest i've seen in my life.Does that matter in the gay community in general?
