Cough

I was due to enter the armed forces and had to go for a medical. At one point the doctor made me strip. He cupped my balls and told me to cough, which I did as quickly as possible. But he did not let go, rather he began to juggle them, then asked me to cough again. He just kept repeating this and asking questions about any pain down there and is everything functioning normally.

Finally he began to basically shake my balls and asked me how it felt. The action of the shaking made my cock shake. This resulted in a fully fledged erection.

He then asked me to bend over for a prostate exam which basically involved him inserting his fingers up my arse. He then reached round and began shaking my balls again but also holding the base of my cock. His fingers up me resulted in a sensation I had never felt before combined with the shaking it was just too much and I started to cum like a fountain.

He then just calmly said 'everything is 100%, get dressed' then he left the room.

I am now so confused because I am straight but the orgasm he gave me was mind blowing and the truth is I want a repeat performance.
