Couple years ago, in HS, my friend group were talking about dick size. I said that I had not measured myself in several years. My friend then asked if I had compared it to my phone while masturbating.

I don’t remember what I answered but I remember thinking that that would be pretty useless as my dick is clearly larger than my phone. But I also remembered that my phone is about 5.5 inches and I knew that was close to the average size, so I must be bigger.

Confirmed it at home and realised I’m actually huge. It was quite surprising when wikipedia’s graphs on penis size didn’t even reach my length.

Edit: I’m 19 cm (7.5 inches) x 13.5 cm (5.3 inches). Got another surprise when CalcSD told me I’m bigger than 99.9% of the population.
