As already mentioned in the replies to this thread, and many others about penis size here and elsewhere... it "depends" dramatically on many factors, and is more subjective than objective.
We would not consider the OPs example as somehow inconsistent with the "BBC" label, but then again AFAIK there is no medical standard for that term
He's just fine!
Different people will have different personal preferences, fantasies, and experiences, and so their desire regarding parameters like length, girth, appearance, etc will vary. What matters is finding friends that like you, and you them, and then it will be fine
Of course, just like any relationship journey, there will be hits/misses as one meets new people, but just keep trying
My wife's perspective, which shouldn't influence anyone else's personal preferences, is that girth is MUCH more important than length. Although for her there is a caveat that she does have something of a minimum length requirement of 5-6 inches, which I guess puts it right in the range of "average" and therefore is statistically good news for her!
To expand a bit on my wife's perspective, as long as the penis is long enough to fully fill her or "bottom out" (apologies if that's a big crude, but makes the point), then it is long enough, which again is usually 5-6 inches. Although she likes longer penises as well, to be honest anything much over 9-10 inches can cause discomfort in some cases
if the guy can keep it fully erect and hard. And that's an interesting observation she's had over time as well is that some men with very long penises sometimes can't keep their penis rigid enough in comparison to more average length penises. Thus those examples can be less hard, bend and kink (ouch!) with the man having to try really work hard to make it all work out. So there can be advantages and disadvantages in some cases with very long penis length, and so again "average" is probably OK in many cases! That being said, she loves a thick and long(ish) penis, when everything works fine and there's no discomfort, it's fun for her to watch and feel a really long penis as well
REF:
Most men believe that the average length of an erect penis is greater than 6 inches (15.24 cm). This belief is due, in part, to several often-cited studies that relied on self-reported measurements, with means of about 6.2 inches (15.75 cm) for heterosexual men and even greater for gay men...

I have no idea about the scientific rigor or sources of the following, but interesting and it seems that USA is itself "average" which shouldn't be a surprise given that the USA is a nation of immigrants from all nations
