For those anticipating a trip to Amsterdam, a tip - every other sunday at the Argos, there is a public sex party hosted by "Horsemen and Knights" a club for men with huge cocks, and those who like them. Check out horsemen.nl for some more information.
Is it worth it? I have frequently been asked if there isn't just the situation that there are one or two hung men, and the rest are chasing them - the situation is usually the opposite. The majority of participants are over 18cm - classified as 'A members' when I was in the club - and the measurements are taken by the club officers. The biggest cocks I've ever seen have been at parties in the club. All sex is safe, clean and consensual.
The two largest men I've played with were at these parties.
The largest girth man was a guy who was about 5'9", 5'10", or so - very hairy (curly black hair), strangely long arms, and a stupefying cock. I remember we were jacking each other off, and I realized that I couldn't get my hand around his cock. But further shock came when after jacking his foreskin back and forth, I was playing with the head of his cock, and he pushed his foreskin down over my hand. I literally had my entire hand inside his foreskin, and it was one of those "I immediately shot off' moments shaking like a leaf.
The longest cock man was Rene from Rotterdam who went to the parties occasionally. He was bigtime into muscle guys, and drooled when I walked by. Tall, "big-boned" Dutch, lean, and little hair, I stopped and started playing with him, and sucking. His cock soft was as large as mine was hard, and as I sucked it fortunately it didn't get super thick, it got longer. And longer. And longer. If you have had sex with a guy with a big enough dick going down your throat, there is a moment when you get very far beyond suppressing a gag reflex and so on, and you literally feel the cock get close to your stomach - there is an amazing pressure deep inside your chest. When Rene pulled out so I could breathe, I played with his balls while gasping, and then I realized that, holding his balls, his cock hung down the full length of my arm with the big head nestled up above the crook of my arm (elbow). It was around 13" or 14" long, and I wasted no time getting breath back and restarting the session. Just really, really obscenely long.
Enjoy
