Embarrassing moment

My cock is very small. About 1.5 inches small and maybe 4 erect. When I was 17 I was a virgin simply because I was ashamed of my cock. A girl befriended me and we eventually became intimate and she assured me my cock was average. At our 17 year graduation party we rented a hotel and we had been into bondage sex a while. She stripped me and handcuffed me to the bed and I was blindfolded. When I took the blindfold off 18 fellow classmates both boys and girls were in the room. For some reason since that day I’m turned on by small cock fascination.
