Though PE may contribute to some minor degree, the main contributor to this is simple genetics. I have hair on my penis all the way out to the circumcision scar. As I have aged, the hair on the shaft has grown in more and more and this is part of aging. I as a whole disagree with shaving, but on occasion it can be a necessity depending on sex acts anticipated.
This is a hit and miss and some men who are otherwise smooth can have this trait and some who are hairy can be smooth. Both my other half and my Nephew are very hairy people. My other half has no hair on the shaft of his penis, but my Nephew came to me asking about his. He also has this genetic trait and it was explained to him. Do not consider this as a factor in your PE routine either way. I have not been active in PE for years and the hair on mine has multiplied in spite of this over the years.
