Pulled Muscle

I went to the physio with a pulled hamstring muscle from playing rugby. During the first session I was in my boxers faced up, he started to feel the front of my leg. I dont know how or why (no inappropriate contact) I just got a full blown hard on. I just did not know what to do.

He just ignored it and carried on. He moved his hands right up my leg to within a couple of inches of my balls with that my hard on just popped out my shorts for all to to see and I just came right there with absolutley no contact form him. I am 100% straight and I have no clue what happened to this day.

I just grabbed my stuff and fled. The most embarrassing moment was me trying to stuff my stiil erect cock into my jeans with the physio saying it happens all the time.
