I'm 6'1" and have a thing for tall guys. I've met a few tall guys that were well hung. One of them was the foreign exchange student we had one year. He was 7 feet tall and the one time I got a good look at his dick I was put to shame. His dick soft was bigger than my dick hard.
Another tall guy is a guy I've talked about on here before. I met him when I was working at the adult bookstore. He is 6'6" and used to come in every night. I like tall guys but he did nothing sexually for me. At the time, he had hair that hung down to his ass and that was a big turn off for me. But one really slow night, he came into the bookstore as usual. He walked through the booth area and saw nobody was back there. After a while, I heard the door chime go off when the employee entrance to the booth area is opened. I looked over and saw he had walked through the door. I told him he couldn't be back there when I noticed his dick was hanging out. His dick is 9" and VERY thick. I went over and sucked his dick and gagged on it. He had a thing for forcing it all the way down and holding it there. That night happened about 25 years ago and I still mess around with him. I've learned to deep throat his dick and I can take it all the way down with no gagging. Sometimes he loves to try and shove his big balls in my mouth while I have his dick down my throat. It stretches my jaws as much as I can and I know my teeth are scraping his balls. But he really gets off on it and I really enjoy the feeling of his dick and balls completely filling my mouth.
But I have also met some tall guys with smaller or average-sized dicks. One of the first guys I ever dated was 6'5". His dick was 4 to 5" and looked super small on his tall body. And another guy I dated for a while was 6'3", big ears, big hands, big nose, size 12 shoes and 5" when hard.
