What is the secret?

Few male pornstars work very hard 
For example this guy.
I think he has sex at least once a day. My question is how his penis always looks so fresh
When i have sex few days in a row my dick is totally ruined. My girl is very wet during sex but it last long.
Is there some medicine he use? I dont see he use oil or vaseline during sex. What is secret?
I would like to know to ease myself
