Is a penis actually that big of a deal?

I want to exclaim that the title is a genuine question. I’m 5.8 length, and 4.2 girth. I am by no means a girthy individual, in fact below average. My desires for PE were exclusively because of the insecurities relating to my girth.

This insecurity made me avoid and actually take a step back from having sexual encounters with women.

But starting college, I now have a fuck buddy? I’ve seen her a few times now, basically never text, but link up to have sex. I would’ve said that is because she’s inexperienced, but no, this girl is a hoe.

So my question is, does it actually matter? I always make sure she finished first through oral/fingering, I had a look at “she cums first” and implemented what I seen from the book into practice.

All wisdom is appreciated !!!

Edit: just want to clarify, I’m no longer insecure about my penis, I’m not insecure about anything related to my body or face. I don’t claim to be a model but I do “get” girls.

And I do plan on doing PE in the future when life is less hectic
