Was he given to nudism in nature because he started too potent and virile to confine and hide his genitals in clothes? Did he start living wild and free and it was so good for his gonads that they grew more strong and fertile than the average man's as he got in touch with his maleness? Either way, when receptive skinny dipping couples run into him, hopefully he shares his sexual giftedness with all the willing women. In some more sex-positive cultures, a man who withholds sex from a married woman who wants it is seen as mean and "stingy with his genitals."
