When I climbed on to the model stand naked for the first time I had to concentrate on not getting aroused, I was successful but it was not easy . I focused on providing assortments of gesture poses and longer poses that showed emotion and were interesting to draw. My confidence in my abilities was high. My ability to ward off spontaneous erections the moment I felt the stirring inside. That all was about to changed while posing for anatomy class . While reclining on box totally naked with bright spotlights as bright as daylight. I was surrounded by eager student artists standing as close as possible to the edge of the platform. Placing my privates at eye level if you can imagine that. This was going to be unavoidable I thought to myself. I knew without any doubt what a turn-on this would be for me. I felt warm and butterflies in my stomach, within seconds, my penis was lurching furiously to the beat of my heart which I could actually hear. I closed my eyes, blushing, I thought, I am fired I know it. To my surprise I heard the professor say oh, wonderful, here we can see the significant changes during arousal. Note the tightening of the scrotum as the penis prepares for ejaculation . With all students eyes on me, as they studied every detail I was at a level of arousal that I had never been before. sensation rippled through me. I thought to myself, I can deal with this, I continued the pose even when I felt flow of pre-cum flooding my urethra. I have experienced the most intense arousal ever while posing.
