So I get the idea that all dicks are nice and it's more about skill both with you penis and in other areas that most gets a girl off (like oral) but I am legitimately curious, if my dick is nice sized? Or just overall good or bad?

Anyhow. I have a hard time measuring the girth of my tip so imma just skip over that, so at what is the widest part of my penis, just below the tip I am 5¹/⁸ in. Then I get a bit smaller, and am more around 4⁷/⁸ but on the shorter side of it. And the base of my penis is not as wide but has more girth, with it being about 5¹/⁴. My length is 6in nbp. With that info, do I have an at least okay dick? I honestly don't wanna be about to have sex one day and the girl I'm with be disappointed.

Any and all solid advice/help is welcome, and I thank you I'm advance

Edit: I know I cannot increase the size of my penis, and I'm probably done growing (I'm 18) but I guess I worded this wrong, what I really want to know is if I'm average, below average, above average, that kinda stuff, which is the entirety of that stuff lol, again thanks in advance
