This is a serious question. On off days I do static stretching for my whole body holding each stretch for 30 seconds. By the time I get done stretching legs I feel a warm pleasurable feeling in my testicles that I really can't explain but it feels like a major libido boost. One time it was so intense that after finishing my ham stretches I was laying on the carpet and had to "lend myself a proper hand" if you catch my drift. Any clues as to what's going on?
