Nothing unusual from what can be seen - it is possible the general condition of the skin can be improved on.
It looks like he is circumcised, so with this natural hydration has also been removed.
This can be improved upon by trying to reduce exposure to soap and other forms of body wash, particularly when showering. Hydration quality can be improved upon by the regular application of liquid coconut oil, for skin, rather than hair - good quality ones do not cost very much, and all that is required is a very light coating. Best time to apply is after drying himself after a shower.
Coconut oil can also be used as a lube for masturbation or sex, again a very light coating is all that is required. DO NOT use the oil with condoms!
Do not expect to see much change in the quality of after just a few months - this will be a very lengthy process of slow change if the coconut oil is used on a regular basis.
