I recently came home from a vacation. My hotel had a sauna and sundeck where any guys could visit. I almost everyday go to sauna and steam room and I got the chance to see and feel a lot of cocks. This is in no way scientific, only my own experience among the guys who visited there. Very many I got the chance to wank and make hard. Myself I'm not the biggest guy around with 18x16 cm. Maybe just over average. In sauna most guys had a smaller than mine. A few even what you could call a micro penis. One arabic looking guy, quite tall had among the smallest, size like my thumb, just about 7 cm. Another small guy had quite big, just a little longer than mine. Generally Chinese guys had very small ones, but also a couple with bigger, 16-17cm. Generally the old guys had bigger than the younger guys. Only many older didn't have very hard erections. Very few black guys and none of them had my size or bigger. One Thai guy that visited quite often had a big and very nice looking cock. He was in the 30s and just bigger than me. He was one of the guys who didn't let just anyone touch his cock. Only a couple of same aged and younger guys could touch. I also saw him fuck a few guys. I got the chance to fuck a couple guys and fun when you you let it slide in and go balls deep, the bottom guy moans ooohhh.... you're so big! None of the black guys outsized me there this year. Before covid there were a Caribbean black guy that was huge, 23-24 cm! I'd say most guys this year were 14-17cm in size and quite a variety in sizes. Fun was it anyway. As I mentioned nothing scientific, just what I experienced about the guys visiting there!
