This is something that happened to me when I was 12 years old. I was changing in the men's locker room getting ready for Karate class. it was the first class of the day and i was really early. one of the instructors came in and asked if i needed help tying my karate belt. Most Karate places want it done a certain way, so I didn't think anything of it and agreed. I had the top and bottom already on, just not the belt. He locked the door, came to me and knelt in front of me. He told me he was going to tuck the top in so he pulled the pants down a little. He then grabbed both my boxers and bottoms and opened them up so he could see my penis. I knew what he was doing and did not stop him. Up to his point I had never thought about another guy, but it didn't bother me that he was doing this. Then he proceeded to ask me if I had my yearly check up of my balls. I had recently gone to the doctors and told him i had. he said he was going to do it anyways to be safe, so he grabbed both my balls and told me to cough. All this time he was starring at my balls and penis like he wanted to eat them up. I am uncircumcised and he even "checked" my penis by pulling my skin back. Then there was a knock on the door and the fun stopped. I don't consider myself gay, and i have never had a gay experience but i have been thinking a lot about playing with a penis. I wish that day would have gone further, but now all i can think is fantasize. I don't have the balls to ask a guy for anything.
