Nah... you're still quite a bit above the 4.6" average, mate (I'm about the same as you, 5.3"). While I would like a slightly thicker cock, I've read problems can arise if it's TOO thick (6"+)... especially with BJs and girls/guys finding it uncomfortable. And on the plus side for us "thinner" guys - according to a recent survey, girls said the ideal girth size is 5"... 😁
